CleanRam is one of those essential Windows Mobile utilities.  Back when I had my TouchPro it would keep it running smooth with one cleanup a day.  If you have not already downloaded it now it your chance to try the new version out.

Quite possibly one of the best apps available today to keep your device running smoothly just got updated. XDA member ronenpgjust released an update to his famous cleanRAM  app for Windows Mobile. In case you are not familiar with it, the app is used to reclaim program memory from apps running in the background that either do not need to be running or that simply doesn’t close completely upon exit. A nice side effect of this app, is that if there are non responding programs, this app will close them and save you from having to do a hard reset, which is a nice perk if you have devices like the HD2 where the reset button is under the battery cover.
