I picked up a Droid X today at noon and within 3 hours the entire screen started to jiggle/shake verticly. I rebooted, removed the battery, nothing helped. The boot screen did it also, so i'm sure its a hardware issue. Never installed an app. I can't say for sure, but it happened after I sync'd music with the USB cable.
By the time I made it back to the Verizon store they were sold out. So i'm sporting an original Droid till they get more stock. Pissed but I guess it could of been worse.
Any word on if this is a common issue? My googling shows that the original droid had simmilar issues.
