Hello, just got the 3G and took my first generation Iphone home to restore and delete all apps that were put on by me to give to my sister.

On the first generation Iphone it reads:

Version 2.0
Firmware: 04.05.04_G

Have been trying to use iTunes 7.5 to do a restore back to 1.1.4 by using the Shift + restore button with no luck.

Any ideas have been working on this for five days straight now, just want to get back to the old firmware of 1.1.4, and then jail break it like I did when I first got the phone back in March of this year.

Any ideas or suggestions would be greatly appreciated.
