Hi, I am new here and to my blackberry 8120 and am trying to get the most from the battery life. I do not have a data plan so some applications are not needed. I do need WiFi on so I can get a signal in my house. I have the lastest software version 4.5.0.124 tmobile and have turned off GPS and Bluetooth. I deleted AIM, Google talk, Windows Live, Yahoo mess. I turned the screen down to 50% and 20 seconds. Any other applications I should get rid of or other tricks to optimize the phone?
