Background activity cost me $$$, please help!
Hello,
Recently I've upgraded my pearl 8100 for from original OS 4.2 to 4.5.0.99. It works fine but there is a serious problem now. Every two hours the device connects to the internet. I don't know how, don't know what does it doing. Just return from an international trip and got extra $80 charge for the roaming data but didn't used it no single time, checked my recent usage today, same thing - every two hours is data connection.
GPS is turned off, google apps closed, AIM+ turned off, no other applications are installed. T-mobile c/s didn't help. Please help me to find what's go on?
Thanks.
