Ihpone wanting to convert it for tmobile, teach me

[Trinirspeed]

Ok so I want to use my tmobile plan and make calls with my tmobile stuff on my iphone( that is what this section is about right?). I know you have to jailbreak it and unlock it. Other than that I don't know much, if you can please make up a kind of tutorial for what to do. Any one have any tutorials? Also I will be able to use my iphone and make calls with my tmobile stuff right?

Look at the top of the webpage, and you'll see a big W and under that "Guides"

Well after you unlock the phone you need to go to settings>network. On the network page you will see "APN", type in wap.voicestream.com to activate Edge. Ignore username and password. Exit to the home screen and you'll be good to go from there.
