no you cant use t-mobile sim in at&t locked mobile. if else you need to use it you need to unlock your phone. for unlocking there are many ways. you can use codes or softwares or hardewares. it depends on your wish and your economic status. if you ask me i would you suggest you codes as the best way. because i had an experience of unlocking my phone through codes. its the easiest way to get your phone unlocked. i bought the codes from Classicunlocking.com. you can either get the codes from your service provider(at&t) itself.

once you unlock your phone your contract with at&t will get ended. i think you will not receive any bill from them thereafter. and yes you will be able to use all your blackberry applications as well
