Thought it would be helpful to list bugs and solutions. I've had this 9900 for two weeks now, and although it is a good phone BB OS 7 is buggy.
1. Proximity sensor constantly blinking after call is ended - Battery pull
2. Google search images not clickable - found no solution yet
3. Phone boots in silent mode - Have to manualy change to normal almost everytime, no solution found
4. When browsing, cant get the cursor to go all the way up, where the address bar is - close and reopen browser
5. When browsing, using the back button closes the browser - no solution found
