my new 8520 keeps shutting down, the battery icon is full but I have to keep taking out the battery to get it to reboot, it was on T-mobile but my wife wanted o keep her old number & network so I had the phone unlocked & it is on orange, also even though it says its connected via Wi-fi to my home network I am unable to browse,
can any one help? ps the orange sim that is now in the unlocked T-mobile phone was not from another Blackberry etc, so even so I can make n receive calls should I get "blackberry sim"? & what are the reasons/differences in doing so?
thanks all, Bacospoil
