    3. The Market of Japanese Cellphones œ {Ruby c200 8 Sf[^ has evolved Exclusively, œ { Œ ^ Cg Ł just like Galapagos. œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł Photo taken by Kath B http://flickr.com/photos/kathb/2196643434/ œ { Œ ^ Cg ¨
    4. Japanese mobile phones have a lot of fascinating features ... œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    5. However, these features are provided with Cell-phone-operator-specific specifications, œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    6. which is sometimes undocumented. œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    7. Example. Requesting GPS location of device: œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    8. for DoCoMo: <a href=\"[URL]\" lcs>GPS</a> for au: <a href=\"device:gpsone?url= [URL]&amp;ver=1&amp;datum=0&amp;unit=0 \">GPS</a> (officially undocumented) for SoftBank 3G: <a href=location:auto?[URL]>GPS</a> for SoftBank 2G: <a href=\"[URL]\" z>GPS</a> œ {Ruby c200 8 Sf[^ for Willcom: œ { Œ ^ Cg Ł <a href=\"http://location.request/ œ { Œ ^ Cg ¨ dummy.cgi?my=[URL]&pos=$location\">GPS</a> œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    9. Of course, the responses are also in various formats! œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    10. I guess you shouldn’t want to know them! œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    11. In short, œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    12. working on websites for Japanese mobiles is œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    13. collecting boring “know-hows.” œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    14. But we cannot give up the fascinating features of Japanese mobile phones ... œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    15. Motivation: want to build websites for Japanese mobile phones in Rails way. œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    16. My answer: œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    17. for DoCoMo: <a href=\"[URL]\" lcs>GPS</a> for au: <a href=\"device:gpsone?url= before [URL]&amp;ver=1&amp;datum=0&amp;unit=0 \">GPS</a> (officially undocumented) for SoftBank 3G: <a href=location:auto?[URL]>GPS</a> for SoftBank 2G: <a href=\"[URL]\" z>GPS</a> œ {Ruby c200 8 Sf[^ for Willcom: œ { Œ ^ Cg Ł <a href=\"http://location.request/ œ { Œ ^ Cg ¨ dummy.cgi?my=[URL]&pos=$location\">GPS</a> œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    18. after for all Japanese mobiles: <%= get_position_link_to \"GPS\", :action=> ... %> œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    19. Jpmobile is introduced in ... œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    20. Who am I? œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    21. SHIDARA Yohji dara ‣ Jpmobile the author of Jpmobile ‣ http://d.hatena.ne.jp/darashi http://twitter.com/darashi in Japanese) ‣ born in Sapporo, live in Sapporo, love Sapporo -- 1.5hrs. from Tokyo by air œ {Ruby c200 8 Sf[^ ‣ a graduate studentœ { Œ ^ Cg Ł ‣ Ruby Sapporo Staff œ { Œ ^ Cg ¨ ‣ RubyKaigi2008 Staff œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    22. My recent work: œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    23. http://buzztter.com extracts buzzphrases from twitter.com œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    24. By the way, œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    25. I love soupcurry! (a typical Sapporo food) œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    26. œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    27. œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    28. so that I made a website: œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    29. œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł http://soupcurry.info œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    30. œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł http://soupcurry.info œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    31. You can find the nearby soupcurry restaurants with your mobile (using GPS). -- if you are in Japan ;-) œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    32. You can find the nearby soupcurry restaurants with your mobile (using GPS). -- if you are in Japan ;-) œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    33. The reusable component dragged out from soupcurry.info is the origin of Jpmobile. œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    34. Features of Jpmobile œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    35. Detecting mobile phones and its operator œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    36. is the most fundamental procedure to handle mobile phones œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    37. It’s not so easy ... Various User-Agents: ‣ DoCoMo/2.0 SH902i(c100;TB;W24H12) ‣ KDDI-CA32 UP.Browser/6.2.0.7.3.129 (GUI) MMP/2.0 ‣ SoftBank/1.0/910T/TJ001/SN000000000000000 Browser/ NetFront/3.3 Profile/MIDP-2.0 Configuration/CLDC-1.1 ‣ Vodafone/1.0/V903SH/SHJ001/SN000000000000000 Browser/UP.Browser/7.0.2.1 Profile/MIDP-2.0 Configuration/CLDC-1.1 Ext-J-Profile/JSCL-1.2.2 Ext- V-Profile/VSCL-2.0.0 œ {Ruby c200 8 Sf[^ ‣ J-PHONE/4.3/V603SH/SNXXXX0000000 SH/0007aa Profile/ œ { Œ ^ Cg Ł MIDP-1.0 Configuration/CLDC-1.0 Ext-Profile/ JSCL-1.3.2 œ { Œ ^ Cg ¨ ‣ Mozilla/3.0(WILLCOM;KYOCERA/WX310K/ 2;1.2.2.16.000000/0.1/C100) Opera 7.0 œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    38. with Jpmobile, <% if request.mobile? %> from mobile! <% else %> from PC! <% end %> œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    39. case request.mobile when Jpmobile::Mobile::Docomo # for DoCoMo when Jpmobile::Mobile::Au # for au when Jpmobile::Mobile::Softbank # for SoftBank when Jpmobile::Mobile::Willcom # for Willcom when Jpmobile::Mobile::Emobile # for EMOBILE œ {Ruby c200 8 Sf[^ else œ { Œ ^ Cg Ł # for PC œ { Œ ^ Cg ¨ end œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    40. Switching templates for mobiles œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    41. If you want to switch templates for PCs and for mobiles, or for each operator, œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    42. just put mytemplate.html.erb and mytemplate_mobile.html.erb, or œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    43. put mytemplate_mobile_docomo.html.erb and mytemplate_mobile_au.html.erb. (DoCoMo and au are cell-phone-operators) œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    44. Supporse that we have these templates. mytemplate_mobile_docomo.html.erb mytemplate_mobile.html.erb œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł mytemplate.html.erb œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    45. Access from PC: mytemplate_mobile_docomo.html.erb mytemplate_mobile.html.erb œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł mytemplate.html.erb œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    46. Access from DoCoMo: mytemplate_mobile_docomo.html.erb mytemplate_mobile.html.erb œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł mytemplate.html.erb œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    47. Access from mobiles except DoCoMo: mytemplate_mobile_docomo.html.erb mytemplate_mobile.html.erb œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł mytemplate.html.erb œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    48. Getting position of mobile-phones œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    49. in a view: <%= get_position_link_to \"GPS\", :action=> :gps %> in a controller, ‘gps’ action: request.mobile.position.lat œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨ request.mobile.position.lng œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    50. Getting production-numbers and/or subscriber-identifiers. œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    51. It should be frustrating to input the password with your mobile every time you are going to login. œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    52. Usually the identifier of the device or the subscriber can be obtained. œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    53. Of course they are based on the various specifications! œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    54. with Jpmobile, request.mobile.ident_device request.mobile.ident_subscriber request.mobile.ident = ident_subscriber || ident_device œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    55. Note that they are not creditable because these identifiers are just passed as plain text. œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    56. The security will be slightly improved with combining IP-address verification. œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    57. Validation of IP-address range œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    58. We may want to block PCs for some (marketing?) reasons, œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    59. or we may want to check if the identifiers (for a device or a subscribe) is surely passed from mobile. œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    60. The operators provides the information of the IP-address ranges on the website œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    61. of course in various formats, and even worse, usually they are not machine readable (dirty scraping is needed). œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    62. Since Jpmobile contains the tables obtained from these machine-unfriendly websites, œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    63. Just do request.mobile.valid_ip? œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    64. Adding session IDs to URL and FORM œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    65. Some devices does not support cookies. œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    66. For them, you need to pass the session ID via URL and FORM parameters. œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    67. class MyController < ApplicationController trans_sid end œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    68. Getting specs of the screen œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    69. The screensize differs according to the model. œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    70. In order to optimize the output, we need the information about the screen. œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    71. The information may be passed via HTTP header, or not. œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    72. We need to scrape the official websites in case that the information in the header is not available. œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    73. request.mobile.display.colors request.mobile.display.width request.mobile.display.height œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    74. Conversion of the Emoticons œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    75. Lots of lovely emoticons are available in Japanese mobiles. œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    76. Each operator have own set of emoticons and own encoding. œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    77. The specifications are so complex that I can make another presentation. œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    78. The mappings (between operators) are also complex and not publicly available in machine-readable format. œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    79. Jpmobile maps all emoticons (of all operators) into Unicode Private Area, and œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    80. the output is transparently converted into the format appropriate for the target device. œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    81. in a controller: class MyController < ApplicationController mobile_filter end œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    82. I’m going to add the feature to send emoticons PCs with embedding images. œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    83. Some mobiles do not support UTF-8 or stop sending emoticons under UTF-8 communication. œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    84. We need to communicate with them in Shift-JIS (a legacy but one of the most commonly used encoding). œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    85. in a controller: class MyController < ApplicationController mobile_filter end œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    86. Summary: œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    87. Japanese mobile phones have a lot of fascinating features. œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    88. But we need lots of boring know-hows to build websites for Japanese mobile phones. œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    89. Jpmobile helps you! œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    90. Finally, I want to ask your help: œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    91. I’m a student, so I don’t have many mobile-phones to test Jpmobile on. œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    92. I often ask my colleagues for help, paying a canned coffee. œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    93. So, if you find out some problems or if you make any improvement of Jpmobile, please let me know. œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    94. It may take long, but I’d like to work on it. œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
    95. œ {Ruby c200 8 Sf[^ œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨ http://jpmobile-rails.org œ { Œ ^ Cg Ł œ { Œ ^ Cg ¨
