I think this has been going on for a few days, but I just realized it last night (BEFORE I received the Gingerbread update, I have the udpate now) I can send texts just fine, but can't receive any at all. I get no notification, nothing. I have tried to send myself SMS and MMS messages from my girlfriend's phone (A Samsung Fascinate through Verizon), two different websites, and my own phone. Nothing. Everything else on the phone works fine, calls, internet, etc.
My data is turned on and I have a strong signal.
I did numerous restarts, including battery pulls. After one of the restarts, I got the Gingerbread push, so I downloaded it. No change. I did a factory reset, no change.
I was using the stock messaging app, so I downloaded SMS Pro, and no change still.
I'm about to call customer service, not really looking forward to that!
