I have tmobile on my 3g iPhone. I ordered a turbo sim card and inserted it along with my tmobile sim. With the turbo u don't need 3g. Also had to tweak my tmo plan and add a data plan (I originally had a sidekick) to have full service. Now I do occasionally experience the " no sim" MSG but it's usually if I run into a dead zone, am underground, etc. I just switch to airport mode and switch back instead of resetting the phone. Also try internet2.voicestream.com as ur apn. With tmobile you have to talk to a rep from "tier 3" LOL good luck
