I did not drop it, no moisture. The phone is unlocked, so I am not tied up to a carrier. I went to BB repair shop, they are going to test it. Can I return it the RIM as it is unlocked? I used it for a month and it quit
You might need to update/reinstall the OS. Sometimes a persistent lack of network is a sign of corruption in the OS but not enough corruption to give you the 507 Error screen or completely crash the BB. Just enough to screw with the BB's ability to find a network.
