You need to unlock an AT&T network locked iPhone to use T-Mobile SIM card to it. Jailbreaking is not a must to unlock your iPhone in safe unlocking methods like remote unlocking service. You can get the remote unlocking service for an iPhone from Simpleunlocking.com at affordable cost with easy unlocking guide. This is a permanent unlocking method and does not require a jailbreak too. Good luck mate.
