I'm trying to downgrade my iphone 2g from 2.0.1 to 1.1.4.

I am following online instructions (circa 2008), which instruct me to restore 1.1.4 via iTunes 7.5

I've downloaded itunes here:

Old Version of iTunes 7.5.0 Download - OldApps.com

Then I downloaded the 1.1.4 firmware online.

However, when I start my iPhone in DFU mode, I do not see the "Restore" Button.

Instead, I see the device located on the Left side, but in the main window, I see a normal itunes screen listing my music on my hard drive.

What am I doing wrong? or has apple surreptitiously disabled this feature of 7.5?
