I hear ya.
What's up Doc?
The Manager at the Sprint store did say that PRO2 seems to not have this issue.
I got my first Diamond in October 2008.
I am on my 4th Diamond.
2 Diamonds got the Worms
and 1 Diamond had a magnet that dislodged.
3 failures in 17 months. Not such a good track record
BUT I still like the Diamond. There is nothing else that Sprint has to offer that I would be happy with.
