Some good news for iPhone 4 users who are waiting for an unlock on iOS 4.2.1, baseband 3.10.01 and 2.10.04.

iOS 4.2, at least from what information we have so far, is slated for release this Friday and it’s going to be a significant update for iPad (not so much for iPhone / iPod touch, though). And of course, there’s going to be a jailbreak to accompany the new iOS version. Here’s all you need to know.

In a reply to one of his many followers on Twitter, MuscleNerd of iPhone Dev Team has confirmed that ultrasn0w unlock for iPhone 3GS and iPhone 3G on iOS 4.1 and iOS 4.2, with 05.14.02 baseband will be released in a day or two at most, once iOS 4.2 is released to public.

Great news for iPhone unlockers! It seems like Sherif Hashim has managed to crash the new 05.14.02 and 2.10.04 baseband which can ultimately lead to an unlock for iOS 4.1 and iOS 4.2 for both iPhone 3GS and iPhone 4 users.
