firstly i would like to say use power search before opening a thread...
secondly i would ask you.. do you know how to reflash!!! you will better understand how to or else its very dangerous thing ... PLEASE DONT TOUCH NITDROID STUFF UNTIL YOU KNOW HOW TO REFLASH YOUR N900...D:

sorry for bold letters... but i installed nitdroid about 10 times and needed to reflash at the end of the day...

anyways best of luck... /that really matters/

p.s if you use win7 64bit its really a big headache at te first time to reflash..
