Here is a bit of news for those of you with the following devices 8100/8120 & 8320 on T-Mobile, Tmonews is reporting that beginning February 15 customers can get their trackball replace. That is not a bad deal if is true, since replacing a trackball can cost you around $5 to 10 dollars if you buy online & do it yourself. I know that after a while the trackball gets dirty or simply stops working do to all the grime it accumulates. So let us know in the comments if you have been able to get yours replace?. If you don’t want to deal with a new trackball maybe you can use this to get a cheaper upgrade to a 9700
