iphone 3gs to tmobile....help?

[Oyeve]

I have an iphone 3gs version 4.2.1 (8c148a) modem firmware 05.15.04 and would love to get this to run on tmobile so I can give to my gfs daughter. I ran greenpoison on it and have cydia but I have no clue on how to procede. I am pretty much a noob on this. Any help would be greatly appreciated!

I have a 3gs coming tomorrow for my girlfriend and will be using this tutorial to put it on Tmobile. You have jailbroken the phone, now you only need to unlock it.
