I have the original 2g version of iphone running os 1.1.3. I wanted to upgrade to os 3.0. I tried following the instructions in
iClarified - iPhone - How to Unlock/Jailbreak Your iPhone 2G on OS 3.0.x Using RedSn0w (Windows)
During Step 2, while restoring the file "iPhone1,1_3.0_7A341_Restore.ipsw", I get an error "iphone restore unknown error" and thats it. Now I am stuck.
What do I do ??
Thanks in advance for any help
