Another good clean up utility is MemMaid (
www.dinarsoft.com). It's not free, but does have a trial period. It also has a reg edit function and is customizable. If you're searching for .cabs in general, you're going to end up with a HUGE list to work through. Probably a better idea would be to decide what type of apps you want on your device and then find out if it's available in .cab form (most are). Are you looking for contact managers? weather apps? backup apps? PIM managers? A .cab is a method of packaging a program, not a program in itself. Hope this isn't too basic.
