I'm most definitely NOT a VZW employee. If a post answered your question, please mark it as the answer.
The My Verizon app is included in the upcoming MR2 OTA update. I installed the leaked update and can confirm it's included AND works!
The update DOES appear to have fixed the reboot issues too! No reboots since I flashed the leaked MR2 ROM approx. 3 days ago!!! Woohoo!
I thought that the compatibility check had been in place. There have been several apps that I have looked for since December that will show up on one phone (and on the web) but not on another phone running a different version of Android. Also, my tablet only downloaded the compatible apps when I initially signed on in March.
