I Think My iPhone 1st Gen Doesn't Have DFU Mode.

Okay I have tried so many time (100) to be exact in trying to put my iPhone in DFU mode but I always get the itunes icon with the white cable, my process of DFu mode is holding the power & home button and waiting 10 seconds then relese the power button and keep holding the home is this right?

That's how I do it, however my iPhone is always off when I do.

u can download ziphone, and use it to put your phone in dfu mode, i had to do that because the button way wasnt working for some reason....so even tho u might not need ziphone for jailbreaking or anything it does ave a dfu mode "starter"
