I know I might get a biased answer here, but I need info from current users. My sister's played with a T-bolt and really likes it. BUT, I know that last few software updates from VZW have caused random reboots and all, but I heard a new update has fixed this. Also, have people figured out practices to extend the battery life to at least 12 hours? So: Is this a good time to get a T-bolt? My sister isn't interested in root, so those kinds of solutions won't work. She's the kind of person to be less technically savvy, and needs things to "just work"
