I buy this Blackberry bold 9700 smartphone in last week and must say that this is best mobile phone I got so ever. Itís is features 3G, 2.44″ TFT display, 3.15 MP cameras, Wi-Fi, GPS, and Bluetooth. Yesterday I upgrade its OS to official OS6 and after doing this task, I got bug on it. I canít able to do any theme change process onto it. Can anybody help me to fix this complex problem? Thanks.
