I have a Tmobile blackberry flip that is about 2-3 months old, and in(was in) very good condition. This morning i woke up and found that the trackball would not 'select' anything although it would still scroll. Additionally the entire keyboard is completely unresponsive. I have pulled the battery out a few times and even the sim card! The phone is working perfectly except for this problem. No water damage or abuse. Anything i can do to revive this thing??? I really don't want to wait a week for BlackBerry to send me a replacement.
