I got the Thunderbolt the day it was released and love it.....I have not had any problems until a few days ago regarding my mobile network. I try to access the internet/facebook/email and It says no connection. When I go into settings profile/wireless & networks I find under mobile network it says connection failed. If I uncheck the box then re-check it I see that it says connected. It only stays connected for a brief time then disconnects again........
Any help would be appreciated!!
