    Hi All,

    Just a quick question, I've tried MRoogle ect but can't find anything helpful - point me to a thread if its already been solved.

    I have a 3GS, fully updated ect, jail broken through the jailbreakme.com, but cydia is pretty pointless with OS4, everything gives me the unhappy face, safe mode.

    I have my 'SHSHs' on file according to Cydia.

    Any idea how to downgrade? Its my only phone now (spare is with my brother) so I don't want the whole stuck in recovery mode that I had when I went from 3.1.2 to 3.1.3 and back down again.

    Thanks in advance.

    Sparknote version:

    Find a copy of the firmware you want, download it, put your phone into DFU mode, restore it within iTunes using the firmware your downloaded. Done
