    -iPhone 4
    -will be relying on an unlock
    -in pwned DFU mode
    -5.1, trying to go to 5.1.1 for the new untethered jailbreak
    -Not sure whether it's GSM or CDMA, but leaning towards GSM.
    -iTunes is on version 10.5.2.11

    I plugged it in and pressed 'Restore and Update' in iTunes- it downloads the update and then gives me the error, 'The iPhone 'iPhone' could not be restored because the firmware file is not compatible'.

    I've tried downloading IPSW's for 5.1.1 from places like iJailbreak and iClarified as well- it won't take them.

    What's up with my iPhone?

    You not alone...

    See here...

    The 1st thing you probably need to do is update iTunes to 10.6.1.7

    Make sure you have the right IPSW file GSM or CDMA.

    You need to make a custom IPSW to preserve your BB for the unlock.

    Use redsn0w to do that, download latest redsn0w, go to Extras/Custom IPSW
    select the 5.1.1 you downloaded. redsn0w will now make a NO_BB IPSW.

    Put your phone in DFU-mode
    In iTunes ALT-restore(mac) SHIFT-restore(win) with the NO_BB custom IPSW

    after you restored use redsn0w to JB.
