If you are still havingproblems try removing and reinserting the SIM or booting with the new SIM already inside.Finally, you can also try to Reset Network Settings from the Settings:General:Reset Menu.***IMPORTANT: For those having trouble. The yellowsn0w application can simply beuninstalled. If you have tried all the hints and suggestions and still have problems just use Cydiato remove the package and then reboot. You will then have service with your locked carrier asalways.***THANKS: A big thank you to all the members of the iPhone Dev-Team for all their hardwork! It is much appreciated by all.
***UPDATES: The Dev-Team has made the following updates...1. Soon you’ll see yellowsn0w 0.9.1 in the repos. It uses a much longer delay to let your SIMcard initialize. If you have problems with 0.9.0, try this one and wait a full minute after you seehomescreen, then reinsert sim card. We need both success and failure reports to tune this acrossthe world, so please be patient (but please also report result!)2. If you are in the U.S. and are trying this with T-Mobile, you must turn off the 3G switch inSettings. Also if you are good with the command line, you can make it much easier by adding theline -q right after the /usr/bin/yellowsn0w line in /System/Library/LaunchDaemons/org.iphone-dev.yellowsn0w.plist (that’s and advanced tip, hopefully someone will make a boosprefs type oftool for it)3. No PIN support yet. Remember how we said this was beta? Well we’re still working out theflow for SIMs with PINs enabled. Please disable any PIN you may have on that SIM beforetrying yellowsn0w, for now..------------------------------------------- 510 comments [add] | 128383 views [digg it] [buzz][del.icio.us] [stumbleupon] [email it]-------------------------------------------Recent iPhone Entries2009-01-01 10:51:17 - How to Unlock the iPhone 3G2008-12-31 19:00:01 - How to Find the Firmware and Baseband Version of Your iPhone2008-12-18 23:52:20 - How to Enable DFU Mode in Mac OS X 10.5.62008-12-12 19:24:26 - How to Copy and Paste Using PasteBud for iPhone2008-11-25 21:25:47 - How to Enable Japanese Emoticons on Your iPhone2008-11-23 20:33:17 - How to Select an iPhone Unlock/Jailbreak Tutorial2008-11-23 01:45:46 - How to Unlock/Jailbreak Your 2.x.x 2G iPhone Using QuickPwn(Windows)2008-11-23 01:12:50 - How to Jailbreak Your iPhone With QuickPwn (Mac) [Updated 2.2]2008-11-23 00:56:31 - How to Jailbreak Your 2.x.x 3G iPhone Using QuickPwn (Windows)2008-11-22 23:09:14 - How to Unlock/Jailbreak Your 2.x.x 2G iPhone (Mac) [Updated 2.2][more][rss]Recent News Entries2009-01-08 23:52:15 - Boxee Alpha Opened for Mac, Ubuntu, and Apple TV2009-01-08 22:02:39 - Four Core iPhone With Firmware 3.0?2009-01-08 17:39:26 - Refurbished iPhone 3G Now Available at Best Buy2009-01-08 16:27:52 - Pixaria Software updates PopCard.me2009-01-08 15:56:58 - Disk Doctor Labs Launches Data Recovery Software[more] [rss]
