It was very late when I posted my first response, so I apologize to isaacng88.
There is another option to save additional application memory for your BlackBerry Bold 9000 device, isaacng88 , read thread BBH-Tool v126.96.36.199
I have personally used the BBH-Tool, when used correctly, it can save you quite a bit of application memory, and so much more.
This option above, is to be used with caution, if not used properly, can potentially brick your BlackBerry Bold 9000 device, so I highly suggest you backup your device with BlackBerry Desktop Software .
I hope this may solve your issue of internal device memory for your BlackBerry Bold 9000 device.
