I upgraded from 1.1.4 to 2.0.1 I had downloaded the 5.99 hack and restarted. It didn't work, I kept getting the $CODE$. I called t-mobile and they do support iphone to a certain extent she tried to help me set it up. I was putting in the wap.voicestream.com and after the restart the cellular data network/edge tab would dissapear.

If you can't see cellular data network/edge and wanna make sure you put the right APN : Just go to settings, general, reset, and reset network settings.

I did all of this and no luck so im back on the 19.99 plan. It is possible that for 2.0.1 they have fixed it so it doesn't work that is what the t-mobile lady mentioned.
