Here is a quick little heads up for those of you who have been waiting for iPhone 4 unlock on 3.10.01 and 2.10.04 basebands. MuscleNerd of iPhone Dev-Team has confirmed now that no unlock will be released until iOS 4.3 / 4.2.5 (whichever is last) is public.

The same source who earlier provided us with screenshots of iOS 4.3 with “Personal Hotspot” feature for GSM iPhones has now dropped another screenshot, this time of About screen, which shows iOS 4.3 Build 8F5148b running on a GSM iPhone 4.

In an hands-on with the just announced Verizon iPhone 4, Engadget has spotted the “Personal Hotspot” feature in iOS 4.2.5, running on the said handset.

Now this is interesting. We all know that iPhone 4 on Verizon is hitting the stores on February 10th, but what we don’t know is that whether or not it will have the Limera1n exploit patched in the bootrom.
