iOS 4.3 is surely on the horizon. That leaves many unlockers wondering whether or not there will be an unlock ready. It's been a while but it appears a tweet from @sherif_hashim may be confirming that the issues have finally been worked out.
Don't go upgrading just yet though! MuscleNerd of the iPhone Dev Team stated earlier that an iPhone 4 unlock solution would not be released until after iOS 4.3 goes public. This unlock would allow iPhone 4 users to unlock their phones on the newer basebands (3.10.01 and 2.10.04).
If all goes well and the unlock does perform as expected, we can probably expect a release a few weeks after iOS 4.3 is released to the public. Any of you unlockers stuck waiting for a solution so you can upgrade? Sound off in the comments!
