I'm a complete 'Apple/Iphone' noob. I've jailbroken Ipads and Itouch's before so I know the basics but thats about it and I really need some help. I recently bought this and I'm just waiting for it to get in the mail, http://www.gamestop.com/elect/cell-...-att-black-gamestop-premium-refurbished/98140 now here is where I need help. My understanding is that only certain base bands can be unlocked. I want to jailbreak, and unlock it to work on Tmobile AFTER updating it to 5.0.1 What steps, precautions, or things should I know? Can someone please help me?
