    It will leave your bootloader at 6.02 and upgrade your baseband to 4.26. Don't do it if you need yellowsnow

    this is a clarification to the original thread... if you ask any of these following questions they will not be answered because that are answered here.

    Q: Will this work on 5.09?
    A: No, not at the moment. the reason that it will not work on any other boot loaders besides 5.8 is the exploit for this version has not been found yet. it is being investigated and worked on as we speak. please be patient.

    Q: Which baseband versions will this work for?
    A: this tool works on all versions between 2.30.03 and 4.26.04.

    this will be added to probably as people ask dumb questions

    Have you actually checked your BL or are you just assuming it's 5.08?

    I'm sorry, but I can't find the 3G Baseband Downgrader in Icy. Rebooted mij iPhone, refreshed the sources, but still cannot find it.
    Can it be that it's renewed/renamed to '3G Fuzzyband Downgrader'? I installed this one, and this doesn't work on 3.0.

    Jailbraking just allows you to install applications that aren't in the app store.
    To use with a non approved SIM you need to unlock.
    If you hadn't updated to 2.21 you could have unlocked with YellowSn0w but as you have you will need a 'piggyback SIM'
    You haven't said what country you are in or what network you are wanting to use your phone on so we can't help much more...

    Will this downgrade the latest iPhone 3G running v3.0 on BETA 5 back to 2.2.1? What practical IPSW firmware file versions are needed here; the versions you mentioned are baseband versions.

    I'm only asking because I know someone knows. Otherwise, I'd spend the 5 minutes in researching it.
