when you say overclocking, what do you mean, like the OS will be able to run stable at 806+??? if thats the case i'll run two OSs on the phone, that wont bother me a bit especially since backup and restores are as fast as they are.
Nick7, thank you for yet another upgrade. this is pretty cool. keep 'em coming! i flashed zefie's kernel on top of v0.3 last night and was messing around with OC'ing. so v0.4 shd be interesting. will let you know how it all goes. thanks for another flavor, dev!
EDIT
v0.4 is not flashing properly. i get an "E:Can't open /sdcard/nROM_v0.4_signed.zip" in custom recovery. will try dloading ROM one more time.
Though it is a good and safe rule of thumb to wipe everything before installing new ROMs. This one my be safe to just flash over previous versions, but you should always wipe everything before you flash a ROM.
