i jailbroke my iphone 4 . 4.2.1 on redsn0w and its tethered...so greenpois0n released an untethered version so i wanna know is it safe to jailbreak my device again without removing redsn0w?
ok so i have this At&t phone unlocked for t-mobile. and i wanna switch to virgin mobile. but i know virgin mobile doesnt have sim cards. is there a way that i can do this?
