Was there a resolution to this? I have a Rezound here doing exactly what this thread discribes. My sim card works fine in other phones. This phone is stock and says it has 4.03 on it.
Yes, there was a resolution. After numerous refurbished Rezounds, I ended up trading the Rezound for a refurbished Motorola Droid RAZR. The Rezound had continual problems, the last of which was that, during a phone call the display would not return once I took the phone away from my face. I couldn't make calls that required passwords, or automoated choices once the call was initiated. At that point, I had had it with the Rezound, and wanted any other phone that would be reliable. The local Verizon store would not provide me with another phone, so I ended up talking to various tech reps, one of which was, in polite terms, rude and ignoarant. I finally ended up with a great rep who listened to my tale of woe, understood where I was coming from, and offered to send me a the RAZR. Since that had been my second choice when I was upgrading a year and a half ago, I went with it.
