Blackberry os reinstall

Lately my blackberry 8800 has been crashing a lot when running 2 or more applications (god knows why). Anyway yesterday I deicded today I would reinstall the operating system to see if that worked.

So I downloaded the os from O2 (my service provider).

Then I installed the os onto my desktop, hooked my blackberry up, launched the blackberry desktop manager and it asks me if I want to update.

I press yes! I let it update takes around 5 minutes.

Now my blackberry is uber fast again I have googlemail, yahoo go, opera mini and beejive all open as I write this.

No idea why it fixed it but who cares? It's fixed!
