Can’t wait to do that and risk bricking my N900 =D
The hack is recompiled kernel… Which means no CPU over voltage which means you probably wouldn’t brick the hardware… That means if something went bad, you can always re-flash the phone (It’s an annoying procedure because I did that a while ago)… Though your phone might heat and do nasty stuff including frying your pants =P
Things were stable when N900 got overclocked it to 900MHz and started to act funny when it went 1GHz (Though someone managed to boot it with 1050MHz)…
Can’t wait to have that recompiled kernel =D
