    As I say in the title, is it safe to upgrade to the latest update of iOS on my iPhone 4 if I hope to jailbreak it someday soon?

    Stay on 4.0 for now.
    Thats what the Dev team is advising.

    Thanks for the quick reply. I browsed musclenerd's twitter feed and the dev team blog but saw no mention. I assumed this was the case though. I have no reason to want the update anyway until a proximity sensor fix is out.

    Yes, ...

    ... the latest Redsn0w unlocks iOS4.0.1 without any problems. I did it and it´s trouble free.

    You update/restore your iPhone 3G with iOS4.0.1, then you just run Redsn0w as usual and point to the iOS4.0.0 IPSW file for the Jailbreak itself (it won´t allow the iOS4.0.1 IPSW file).

    You might have some shortterm incompatibilities with Cydia apps, as some tend to be very strict on firmware versions, like Backgrounder e.g., which won´t install on iOS4.0.1 because it checks for iOS4.0.0 only.

    To keep iOS4 native background wallpapers and multitasking, I strongly recommend installing iMemory VM enhancer and deleting language packs and unused launchd daemons - the 3G speed won´t scream, nevertheless shout again loud and clear, so to speak ;-)

    Thank you for your reply, but I'm using an iPhone 4 here, patiently waiting for the day I can jailbreak it, and don't want to screw up.

    Sorry, ...

    ... I thought going from iOS4.0.0 to 4.0.1.

    Well, we all wait´n´bait, "The Jailbreak is near, I see it coming ..."
