I used to get phone signal and 3g reception fine, full bars when indoors at my apartment. I did the 2.2.2 update a few days ago and now i no longer get phone and data signal indoors at my apt or at a few other indoor buildings. My phone shows 4 full bars though, but it just says "No service" so i can't make calls or use data.. any ideas? I've tried a hard reset already too.. Also im on tmobile in NYC.
