i have something to say about all this thunderbolt issues and now the 4g being down. i love this phone, its by far the best phone i have ever owned in my life. does it have issue? of course. but doesn't everything? is your car/truck perfect? that breaks down to doesn't it? how about your computer? it has issues from time to time. cable companies when they release a new product always have issues, till they get ironed out. 4G for verizon is new, still in the infant stage. so yes i expect issue with it. but in time it will be the best ever out there. nothing is perfect in life, give things time to settle down and they will find and correct the problems. yes mine wont switch 3g/4g i have tried reboot, sim card, hard reset and still wont work, but you know what they are working on it, as per the leak that came out. as we read even the leak has issue, therefore they will read forums like this and correct the problem. also experiencing battery problems to. i deal with it, cause i love the phone i have learned a lot from reading forums but the negativity is getting old. i love my thunderbolt, i love everything about it. got to have patience my friends.
