Yellowsnow, the most anticipating and biggest New Year's gift for iPhone 3G community is finally out and ready to be downloaded. Yellowsnow is essentially the ultimate hacking utility to unlock iPhone 3G firmware 2.2 and is specially brought by Dev Team (previously engineered similar tool to unlock iPod Touch and iPhone 2G). It was initially scheduled to be unleashed on New Year’s Eve of 2009 but for some reasons it came out a bit late.
This particular unlock works exclusively with baseband 02.28.00 (it means it works on baseband 02.28.00 ONLY and not the previous ones) which comes with iPhone OS v2.2. So, for those who have pwned their iPhone to 2.2 without a full restore will need to restore to 2.2 directly in iTunes and then use QuickPwn to activate otherwise your baseband might be outdated.
Note: The Yellowsnow application is a 0.9.4 beta so don’t automatically expect everything will run smoothly. Some iPhone users found signal fluctuation after this hack was applied. Use this hack at your own risk.
