like you i have been reading it up on xda forums too. i was going to attempt to try it tonight but abit afraid to do so :O even though i have succesfuly flashed an N95 and a psp before but this is a whole different device!
From what i have gathered so far to flash the rom i need to unlock the cid and hard spl. after i have done that its ready to flash apparently. what i dont understand is hardspl and cid unlocking the same thing? i see various threads merging the same thing
