RE: go on............. I've followed the exact instructions for 6 peoples iphones and its worked every time.
I did it with 3.0.1 installed ITunes updated my phone to 3.0.1 and locked it from previously been unlocked.
Just follow Retals instructions. You don't need to do steps 6 8 and 9 as they are only to allow dodgy apps to be downloaded. (You can always do that afterwards). DONT upgrade to 3.1 sofrware as there is not unlock for this yet. (3.01 is ok)
