I searched the forums here and on iclarified and wasn't able to find a clear cut answer.
I'm selling my 3GS, old bootrom, have SHSH for 3.0 and up.
Getting new iPhone 4 tomorrow morning.
I want to wipe my 3GS and put 4.0/jailbreak/unlock.
In order to unlock, do I need to be on an AT&T activated SIM first? Or does it just need an AT&T SIM in general?
Most tutorials show it on a phone that is already activated on a carrier (Rogers, etc..).
tl;dr do I need to wipe and unlock my phone before I get the new iPhone 4 tomorrow morning?
Edit: I have 05.11.07 Baseband
