Hi,

First, sorry if this question is already in another post:

is it possible to unlock if I have a jailbroken 1.1.2 and I use the program modmyiphone?

If you have a oob 1.1.2 that has the 4.6BL which is should if it was a out of box you can use the unlock MMI posted its Geohot's unlocker just packaged in installer like iclarified's. Of course don't forget to have BSD subsystem installed and open ssh and vterm 100 sense it is already jailbroken, but don't do this method if you are on a 3.9BL
