okay i got my fascinate in september i think? and recedntly it has stoped vibrating altogether. not really a problem for me. but the battery likfe sucks lately and if it dies or i turn it off, most of the time when i turn it on it goes on in "safemode" and i have to take the batteery out and reboot the phone to get it out of safemode. i think im jusdt going to root it and get 2.2. i know this has been asked before but im still very confused. how can i root? probbably a bad question lol and once rooted how hard is it to unroot in case i need to replace the phone?
