iPhone 4 won't restore, device isn't eligible...!?
Very long story behind what I'm about to tell you, so I'll keep it short.
I have a friend who gave me an iPhone 4 to unlock for him, as a reflex, immediately after getting it, I put the phone in DFU mode and hit the restore button. (4.0 restore)
I got an error that looks like this: "The iPhone 'iPhone' could not be restored. This device isn't eligible for requested build."
I don't want to restore it with 4.1 since I won't be able to unlock it. So question is, is there a way I could bypass the whole 'iTunes checking eligibility thing' or is there a way I can restore the iPhone without iTunes?
All suggestions will be appreciated,
Simply hold power and home buttons for 30 seconds until the iPhone exits DFU mode and leave the iPhone at iOS 4.0 - your attempt to restore did not get far enough to make any changes to the iPhone.

The only iOS version that can be restored on an iPhone 4 right now is either 4.0.2 or 4.1.
Use TinyUmbrella The Firmware Umbrella to backup your 4.0.2 SHSH now, when you have a SHSH for an older iOS version you can always restore to that version of iOS on your particular iPhone
AVOID 4.1, if you have restored to 4.1 on an iPhone 4, restore to 4.0.2 via DFU as soon as you can. There is a small window where you can downgrade your baseband while restoring from 4.1 to 4.0.2 (only works on the iPhone 4)
Apple will stop signing 4.0.2 soon, which will close the downgrade window.
