So I just received an iphone 4 as payment for a favor I did for a friend. I currently have Tmobile's no contract plan and I want to keep it because it's so cheap. Just wondering if I have my ducks in a row before I get started... Looks like I have to: 1) cut down my Sim card to micro sim size, put it in my iphone 2) run a program on my mac to jailbreak and unlock 3) restart tethered to my computer, whenever my iphone needs a beboot. is that it? Can anyone help me out and let me know if I missed anything? Any tips or instructions would be highly appreciated!
