To get this damn thing to work, do this:

Run iph4cr.exe and select the day/month/year of your choice.
Paste the SERIAL# onto the clipboard.
DO NOT CHOOSE REGISTER! It will screw things up ROYALLY!

Install Iphone 4.0
DO NOT CHOOSE REGISTER NOW
run iphone, when it says "This will expire on...", choose REGISTER
Paste the SERIAL# into the box and press INSTALL.
Do not select ADD TO ADDRESS SERVICE (I just dont trust that)

It should work that way.. if not, you'll get some weird error when it
tries to run... try it again. I finally got mine to work with no probs.
