Unfortunately, I'm on my 5th, but really 4th:
2 screen popoffs -- warranty replacements
1 bad build: elevated silver bar on pkb
1 order thru Amazon as an interim replacement and returned as Wtty replacement arrived (don't count that one)
1 warranty replacement on order and in process.
I'm very happy w the features and functionality of the device, but this is getting nuts and hours and hours blown. I've never had this experience before w Blackberry.
