- Yes - blackberry use webkit too. Microsoft is the lone hold out\nImportant to note that webkit is not an open source browser, \nbut an open source browser engine kit. \nSafari and Chrome are not identical.\n
- Test, test, test.\nAnalogs are a convenience tool but not a substitute for device testing. \n(turn phone side ways)\n
- JavaScript is important to note because it explains a lot of its shortcomings.\nAll of these tools are free!\n
- Very similar to WEINRE in function. I thought it was WEINRE version 2.0 or something at first\n
- This is a must have if you are supporting the iPhone!\n\n
