Well my experience with the Thunderbolt was short lived. I got it yesterday morning. Battery was so horrible, I am in the center of a 4g area, and th phone would get a 4g signal for 2 seconds or so at a time and then back to 3g. I called Verizon and they said they would have to open a ticket, I said forget it. As for the battery, I charged the device fully before I even activated it. 3 1/2 hrs later back on the charger. Before I went to bed at 3a.m, I charged it again, and put airplane mode on to see it it had anything to do with searching for 4g. Woke up at 7:45 and it was half drained. So this morning I packaged it back up and sent it back. Just going to wait for the bionic.
