MuscleNerd of iPhone Dev Team has managed to unlock his iPhone 4 by a different method than the one shown by Planetbeing (of Android port for iPhone fame) last week. Apparently, there are three methods by which iPhone 4 baseband can be unlocked. The first one was used by Planetbeing and was demonstrated last week. This one by MuscleNerd uses a different technique, after which you could set your iPhone to chose an operator automatically based on availability or set one manually!

The two iPhone hackers will now work together to find out which one of the two methods is fast, and more efficient to use before finalizing the next version of ultrasn0w with iPhone 4 support for public release. The third method is likely going to be saved for future
