I presently have a 7100t thats contrated the white screen of death (sans hourglass). I spent a whole day messing with it and came to the conclusion that I'm better off just getting another phone.
What I was wondering was if I picked up a cheapie 8100 off of ebay, would I be able to move a backup of the data from the 7100 into the 8100 from the same desktop manager?
