Hey guys, I've been holding out on updating my 810 for a while since it's not an official update and some said the battery life is worse. But it really seems like T-Mobile is never going to push out 8.1, so do you think it's worth it to just update to the developer preview? As far as I know there's no way to revert either, so if my battery life decreases because of it or there's something I hate about it, i won't be able to go back. Thoughts?
