-- Posted by T E C H N O at 8:29 pm on Oct. 13, 2008 How are the 8100 series of the blackberry pearl? I had the 8130 for verizon, and the trackball went out after a while, but I think it's because I semi-modded it by taking out the trackball and putting a piece of colored tape to change the color of the trackball... I won't do that in the 8100 for t-mobile, but also, after a month and a half of texting the key board started to get rubbery.. like all the keys would move when I texted.. is the 8100 for t-mobile like that? -- Posted by californication at 8:31 pm on Oct. 13, 2008 If it wasn't for date rape, I'd never get laid. -- Posted by Clara Bell at 8:37 pm on Oct. 13, 2008 I don't see why it would be any different.
