who lied to you?
please explain your comment....
all the new iPhone 4 have this baseband...
are you looking for a jailbreak or an unlock?
the modem baseband is now been written in a different language.. hence the revision number...
so unlockerz will be disappointed for some time, but i am sure there are plenty of new exploits to be had
as for jailbreaks.. p0isixninja has several exploits for tethered and untethered jailbreaks... but it will be some weeks before a jailbreak is released....
