KjjI like my thunderbolt, but that battery extender with door is a little ******ed. Htc should of just made the tbolt slightly thicker and designed it with a slightly bigger battery . The standard battery phone comes with is really small for a big screen 4g phone and the extended battery is a bit much. Htc heard of happy medium? And light seeping through bottom of screen and ledge what up with that? Mine has that and light seepage on top right corner as well. Htc make nice stuff, but quality control isn't there. The battery extender is planned out plot to make $$$ which is cool, but the phone cost enough already and they could of went different route and put in a more suitable size battery for a phone running this much juice. Its hard to get a case while rocking the extended battery and if they did the phone will look like a huge mangled turd. Htc I think should be a little more classy about it's products. I don't know who to blame for the update that causes rebooting randomly I'm guessing htc they create the software. Hopefully they get a fix soon and maybe test it's software before releasing it and not go with a leaked version.
