*Plug in the Iphone
* Open System Properties (in the Control Panel, or right-click "My Computer" and select "Properties"), then go to the Hardware tab and click the "Device Manager" button.
* Scroll down the list until you reach "Universal Serial Bus controllers". Double-click it to expand it, then look for "Apple iPhone" in the list. If it's there you can skip the rest of this. If not, go to the next step in this list.
* Next find the section "Imaging Devices". Double-click it to expand it, then right-click the "Apple iPhone" entry and go to "Properties".
* Go to the Driver tab and click the "Update Driver" button
* When the Hardware Update Wizard opens up, it may ask if you want to connect to Windows Update. select "No, not this time" and hit Next.
* On the next screen, select "Install for a list or specific location" and click Next.
* On the next screen, select "Don't search..." (blah blah blah) and hit Next.
* The next screen should show you two entries, "Digital Still Camera" and "Apple Mobile Device USB Driver". (or similar) Select "Apple Mobile Device USB Driver" and click Next.
* After a while you will be presented with that same "this driver might make your face melt off" warning screen from earlier. Click "Continue Anyway". (Though if you do I can't guarantee that your face won't melt off)
* When the install process finally completes hit Finish, then close out all the windows you've opened.
That worked seamlessly (without having to go into the registery.
