I'm looking for suggestions on how to improve the performance and speed of my Nexus One (AT&T version, Android 2.2.1, FRG83D). Despite all of the newer phones that have come along, I still love my Nexus One and it's THE phone for me. It does get a little sluggish sometimes though. Aside from clearing the browser cache, what else do you do to keep it running smooth and speedy?
