just to let u guys know, i have h/w unlocked my 1.1.2 OTB sucessfully. however it continued to crash when i made a phone call or received since i live in the carribean and iworld did not support it. after spending hours and hours, i finally had 1.1.2 unlocked and upgraded through INSTALLER to 1.1.3. not sure how many have you done that...but as of now the draw backs have been minimal in my opinion. youtube doesn't work, and most installers 3rd party apps don't work. will keep you updated with any other draw backs, one things for sure, i am already pretty satisfied. next thing up, buy a new metal case and antenna cover for my iphone.
