I ran through a full ##786# and cleared my phone's settings in their entirety, including the PST, then I reactivated the phone with ##mymslhere#
Its not for the faint of heart though... I wouldn't really recommend messing with it because if you can't figure out how to get it going again, you'll have to call Sprint and explain to them what you did to deactivate your phone.
I dunno. Could be all in my head. But really, this seems to have fixed all my issues except the RAM issue.
With just HTC Home, Resco Radio, and Opera running, I'm at 3MB free. T_T
