checked my berry and it said (where the service provider is usually listed @ the top) that there was a sim card error. I did a battery pull and fortunately everything worked upon reboot. Anybody else ever have this issue? I have an 8320 on TMO running OS 4.0.5.52. All is well now, but it tripped me out for a second.
Hey jsFett, you should check the T-Mobile site, I believe your running outdated version of OS. I think the latest official tmob release is 4.2. If your interested in that anyway!

This happened to me last week! I did NUMEROUS battery pulls, tried leaving my phone off and NOTHING would fix this. I had to go to a Tmobile store. The lady suggested I get a new SIM, on them .. I did, and it works fine, now.
