1) If I buy an iPhone 4 tomorrow (AT&T / GSM version), will the software on the phone be a version that is unlockable? 2) Would you advise someone who has no idea how to do this, to attempt it? I just want a phone that I can pop sims into when I go to other countries. I know nothing about this hacking or unlocking stuff. But if its as simple as running a program then anyone can do it. Your opinion?
