You likely have an iPhone 3G. The last version of iOS that supports an iPhone 3G is iOS 4.2.1.

Click the restore button in iTunes. Don't select the firmware. iTunes will then download the correct firmware for you.

did that, and got the same message?

'The iphone could not be restored because the firmware is not compatible'???

is it because its still jailbroken???

Put your iPhone into DFU mode (Google it) and restore it in iTunes. That should get it restored to iOS 5.1.1.

If not restore it on another computer then plug it back to yours to sync your stuff over.
