BB Bold :: 9900 Letter Fell Off Of Keyboard?

when I pulled my 9900 out of my pocket, I saw that the letter P had fallen off of my keyboard and into my pocket. No idea how that happened, especially since my phone is in top shape. I called T-Mobile to see if my phone was under warranty (I bought it the first day it was available in California, which was on August 31st, 2011) and if there was anything that could be done. They directed me to call RIM about the issue. I called RIM this morning and was told by the representative that the warranty is at T-Mobile's discretion and that I'd basically have to hash this issue out with them. So I just got off of the phone with T-Mobile, again, and was told that the button falling off wasn't a "known issue with this device," therefore the warranty was void and my only option was to buy a new phone. This is terrible, a $600 phone and within less than a year my button falls off. The sad thing about it is, I also own the 9700 Curve and I had this same issue happen, except it took more than a year before the letter P fell off of that one.
