I have hed my new Thunderbolt for two days. 6 hours after I authorized it, I was checking the Wireless and network settings in Mobile Network and Mobile Networks. I did not change anything, just looking. Later, it would not connect to the internet (no 3G). The text below the Mobile networks option says, "Connection failed". The box is checked. It no longer displays 3G or even 1X on the display on the top of the home screen. I called Verizon tech support and the level 2 technician checked all of my settings and said I could either do a master resset and lose all by setup (contacts and email account creation) or wait 24 to 48 hours and the phone would correct itself. He said this was a known issue. I have waited 24 hours with the phone on just sitting on the counter and there is no change, no 3G service (I am in a 3G area, no 4G). Is this a common problem? Is there a fix that does not involve a master reset? If this is covered elsewhere, excuse me but i did look.
