CrackMem is a free utility for helping to optimize the BlackBerry's memory. It has only been tested on 8xxx series phones.
As you can see it is a windows application.
Please do be careful with Wipe Phone,It needs confirmation before action. It really will brick your phone in two clicks.
If you are unfamilliar with upgrading your phone's Operating System then please Google for post first on how to upgrade or downgrade to New/Older OS properly.
