I upgraded the verizon xv6800 rom to windows mobile 6.1, and now my ringer or vibrate will spontaneously default to no ring without warning. Tech support has no clue. I can't figure out if it is an application that triggers it. It would have to be one that runs in the background.
Would appreciate any suggestions. I have found that Sprite backup will allow you to restore all applications, but must make sure you are running the latest version before backing up to restore to Windows Mobile 6.1.
