i've decided not to install ics because of too many user problems i read on xda thread. if i root the phone in gb now, will i need to unroot it if i want to go to ics or jb in future? i want to remove the useless at&t apps on the phone. plus the stock gb gallery seems to have some memory leak. my battery discharged to just around 40% after 52 hrs or something after last charge (put it for charging now), and in the top 3, the gallery is always there at 30% usage of battery. i haven't even used it, so cant understand.
