I recently upgraded my phone and my wife's. Mine is fine, however hers can no longer show text messages. When you send one to her phone, it blinks for just a second, but when you go into messages none are there .
They are both AT&T 8310 Curve's with platform 2.7.0.40 and I upgraded them to v4.5.0.10
I tried to reload the backup the desktop manager made when upgrading but it says failed in the middle of trying.
