Hi, today im going to buy a white iphone 16g but there is a problem, i have services with tmobile, i want to know if i can unlock the iphone and/or be able to use it with t mobile, if there is a way to unlock it, because i just bought the Blackberry 8120 and i really like it, but i want something more "cute" and what is the difference between 1.1.1 and the 2.0.2 or something like that, what is jailbreak and if someone can help me to see if its worth it having it or not... i will really appreciate it

thanks a lot!
