Yes Armand360, if you boot back to Maemo(Kernel) then nothing is overclocked!

@atilla
I dont think your warranty is gone, coz how are they gonna know you overclocked it.. If it isnt overclocked when you send it in for repairs/whatever. Then i dont think the will notice it..

I had my N900 for 3 months now and i started overclocking it about a month ago lol
