I have an iphone 3GS with
Formware: 06.15.00 and
Os Version: 4.2.1
It is currently tethered jailbroken and unlocked. As you already may know the problem with tethered unlock is I have to attach it to a computer every time i power start it.
It has been very annoying for me so far. I wonder if there is any way, I can unlock it untethered.
Any suggestion/help would be appreciated.
