Hi everyone.
My magical N900 is coming to the end of its glorious life, the camera button died a few weeks ago, and now its having the sim card error

I think ive decided to send it to Nokia as its still under warranty, and see what i get back, but as ive overclocked do you think i should re-flash the firmware?
If so can anyone point me in the right direction as this is one thing i have never done on my N900

Cheers!
