Hi,

I use the 8120. The memory therein is 64MB. Though it is just enough, any new application reduces speed. On checking the memory status you find it goes down to 0 bytes free. But the moment you reboot the device you find MB's of free space.

Is there any way to:

1. Increase the device memory space
2. Clean memory without rebooting. I tried cleaning the browser cache etc without luck.

Thanks for the help.

delete unnecessary media files like BB promotion video and pictures. I released few mb such way

Thanks, these things have already been done by me but no help.

I need to clear the memory which builds up inside when using some applications (eg., cookies when you browse the web)

You can't.
The memory is IN USE while using an application. Its like RAM for a computer. You can't clear it. You have to stop using the application and wait. Or do a battery pull.

try downloading the little app QUICKPULL (it is free and avail on BB App world). This is a great application.
