I guess my family is just lucky. My wife and I both got TBolt's in March. Both are still stock but with different configurations and apps but neither of us have had reboot issues and the battery lasts all day on 3g and most of the day (8 - 12 hours) on 4g. I absolutely love this phone!
My wife and I also both have bolts, other than an occasional reboot (we don't have too many) we love them as well. Battery life is actually pretty good for us.
