I was very excited and would brag about the Thunderbolt but for the past week, somehow my internet SUCKS!!!! I have gone from having 4G 24/7 to 1x if I am lucky. I don't understand what the problem is. I have taken the battery out, the sim card, left it alone for about 5 minutes and replaced everything back and it seems to be getting worse. I don't know what else to do. My wife also have a Thunderbolt and her phone is fine. We stand a few feet apart and while she has full 4G access, I have nothing. PLEASE HELP...........
