Went back to my trusty X a few weeks ago...after a disappointing 4g experience with the Razr. Everything is working nicely, but the device has become noticeably more sluggish. I've done a factory reset, and do not want to root the device. Is there anything else I can do to remove apps, or free up some RAM any other way? The VZW tech support people insist that a task killer is unnecessary. I'd appreciate any thoughts or suggestions....thanks!
