iPhone jailbreaker MuscleNerd, a well respected member of the iPhone Dev-Team, managed to unlock the iPhone 4 using a different method then the first.

Here’s what MuscleNerd had to say on Twitter:

Yay, got the 2nd of 3 ideas working. http://is.gd/dxTwO <- my ultrasn0w’d iPhone4. Now @planetbeing and I can compare.

Planetbeing and MuscleNerd can now compare their unlock solutions to see which one will be used to update ultrasn0w.
