I have a few questions... I am super new to android, but I have been playing with my moment non-stop since I got it last night (had it flown in next day air). I rooted and put a custom rom on my moment last night. Forgive me if these questions have been answered somewhere else on the forum. 1. How do you undo the root for the moment (unroot)? 2. How do you remove the custom rom and go back to stock 2.1? 3. Will wifi tethering make sprint charge you? (I'm pretty sure they won't, but want to make sure) 4. My phone has network errors a lot, and I have to reboot. Do I have a faulty handset or does this happen to you guys? 5. How do you automatically start wifi when a remembered network is in range? 6. In your opinion, did I make the right choice in buying this phone or is it outdated? Should I have stuck with my Blackberry curve 8330 and waited for the epic? (I know it won't get any official updates, but I realized that people are working on an unofficial version of 2.2) 7. Has Sprint said whether or not they will charge the extra $10 a month on the epic? 8. What is a good app that helps save battery?
