Damnit! My frigging-fraggin-frakin' DroidX has taken to rebooting itself many times (but not always) whenever I plug it in to the computer via the usb cable!!!
Apparently many are having this problem but I've never see it before a few days ago.
There is a lot of speculation -- bad/failing sd card(s) -- the Weather Channel App -- a bug in the latest software update (but that was a while ago not just last week). Now the Weather Channel App did get updated (last week I think) and so I've uninstalled it and have not seen the "reboot" connecting since.
Also strange behavior in locking up occasionally and having to pull the battery to get it to come back!
I've had an issue with it occasionally losing it's ringtone (which is downloaded and stored on the SD card) but I've been just "living" with that. (a reboot fixed it)
Man! I love my DroidX but not when it starts this sH*T!!!
