    Hello, Im waiting for the new unlock for iPhone 4 to come out. I was wondering if iOS 4.0.1 affects the possibility of unlocking my iPhone 4 in any way as opposed to iOS 4.0? is it safe to upgrade?

    If you expect to jailbreak and/or unlock, never upgrade firmware until the tools are released.

    Exactly.
    I dont usually update just to update.
    If there's reasons and features enough I will do it. But just so it displays the bars a little taller or different is not even worth my time downloading, updating and restoring everything on the phone.
    Worthless IMO.

    Haven't you learned by now that you aren't supposed to update the lastest OS software without having the say-so or green light from the iPhone Dev Team?

    The iPhone 4 allows baseband downgrades. 4.0.1 didn't have a baseband upgrade anyway, so it won't affect your ability to unlock.

    Really? On the new iphone 4 basebands can be rolled back?
    Very interesting.
    What did you hear?

    MuscleNerd said on twitter that it allows baseband downgrades but that they are "signed even stricter than SHSH blobs." Unless there's a way of spoofing the signature or a weakness in the protocol itself, it won't help for unlocking.

    actually, it changes the sensitivity of the antenna as well. The one bar display can see signals as small as -121 dBm now as opposed to -118 dBm. (every 3dB is twice the power)

    Wow, things get harder and more complicated I see.
    Hope they figure out a hack/workaround for it if possible.
    Downgrading basebands along with firmware would be sweet.

    Thing is, the Chain of Trust is very weak now with so many checks. If on of the lower checks fails, bye-bye iPhone 4 security.

    However, those extra checks also bring in the more complex stuff to do to acquire such jailbreak.

    I hear you.
    They keep making it harder and harder for us but I got faith in The Dev Team;)
