did they ever upgrade the quality of the Touch Pro? i have early version

[tracerit]

I have one that was manufactured sometime last year, probably during the first few batches. There's a part of the phone, right above the VOLUME UP that broke off. now when the keyboard is open, the top screen will be slanted because that piece that broke off was a "stopper" so the phone would not extend too far.

is this something that i can bring in for an exchange? i bought the phone off ebay and it was in excellent condition. i don't have the monthly phone insurance.
