iPhone4 Turbosim & Internet Problem

[NyCzFn]

Basically, my dad bought himself a turbosim and it works great, phone, apps all work. But the internet doesn't seem to be working. Wifi does, but not 3g or Edge. He's with T-Mobile and has the unlimited data plan. I tried putting in all the APN settings like internet2.voicestream.com and whatnot, but nothing seems to work.

The Version is 4.3
Firmware is 04.10.01


If anyone can help me out or give me some advice, it'd be really appreciated. Thank You!

If i'm not worng, They said on the applenberry site that 3G doesn't work on T-Mobile.

Yes I know 3g isn't supposed to work, but isn't Edge supposed to?
