We are doing better except for phone calls - inability to place a call (call repeatedly fails) or receive calls at times...
2 are OS 5.0 and 1 is 4.6 as they are in a corporate environment and the corporation decides when you can upgrade. The bold's that were upgraded to OS 5.0 have to have battery pulls due to a memory leak. How often you do that can depend. After you do the battery pull and the memory comes back... everything runs much better. But that is not the cause of the current problem. I believe it is AT&T - things are better... but we aren't running like "normal" yet.
