When you say cache, do you mean your browser cache or App World....or....?
We have a few guides on the website on how to update the OS http://crackberry.com/blackberry-101...ting-system-os. Though if you haven't updated before, there may be an update available to you using the BlackBerry Desktop Manager.
There is also a more advanced tutorial here but if you following the instructions you should be okay. http://crackberry.com/blackberry-302...-blackberry-os
