For 5 days I've done nothing but read up on iPhones and have learnt alot, jailbroken already with no fuss but am lost at unlocking.
First thing, should I downgrade OS? If so, why and how as have actually tried and I get 1601 error all the time but i know am in DFU mode.
If downgrade not required then why hasn't my current attempts to unlock worked?
I have restored OS3.0 but can't activate as the SIM card is gone.
Also, if I put a different O2 sim in a "carrier" option appears, whats this?
