I sync my Tilt 2 to an XP netbook & a Vista desktop. It runs some things that require unlock files, based on the device ID. Recently, there were some issues with those apps. After a lot of frustrating experimentation, I discovered that the device ID of my phone had, at some point, changed from the original. I then discovered that my phone's device ID was changing each time I made a sync connection with my Vista computer. I'd never seen or heard of this before. Has anyone else had similar issues? How do I stop this from happening each time?
