Okay, so I'm a new android user, and this Optimus is incredible, puts most phones to shame for the price difference. But I started with downloading advanced task manager, and saw my RAM kept going down, and even when killing apps the RAM doesn't go up much to what it was before the app opened. So i started downloading a crap load of apps to help keep my RAM up, but am i over doing it, will the phone close the apps when it needs more RAM? P.S. I also rooted the phone, all i have is AdFree, i don't know what to download to make it any better or more customizable, I'd like to remove a lot of sprint apps and anything that's slowing me down, any advice?
