Hello iphone Genius'! i have a couple of questions that i really hope that one of you guys would give me some advice about it. with that say here i go

i recently change carriers (from ATT to T-Mobile) my iphone is jailbroken with quickpwn and firmware 2.2
i wanna know what i need to do to unlock my iphone so i can use it with Tmobile?
if i do the whole process again with QuickPwn?
do i really need to install the bootloaders (39.bin and 46.bin)
and if i re do it, does the Tmobile sim card has to be in it during the unlock?

seriously guys if any of you can orient me on this i would really appreciate it. i really dont like the new phone that TMobile gave me im so just to my iPhone that i can seem to give it up like that.

thank you all
