I have an 8703e that I bought used this summer. The scroll wheel has broken.
I can't buy a new one through my carrier ($400+) so I'm looking at either a used Curve on Craiglist ($200) or sending this off to be fixed ($100) until my contract allows a new one (11 months). In addition to the scroll wheel, the phone keeps locking up and crashing.
Are used Blackberry's problematic? I don't want to get a another used one that needs repair again.
Get away from that scroll wheel the trackball rules. You can adjust trackball sensitivity and as long as you keep it clean it is better than a mouse on a computer.
One of uncles has an old BB with a wheel I didn't care for it at all and I let him play with my Pearl now he wants one, He just too tight on the wallet to get one.
