    Question Probably a n00bish question but something I'm curious about...

    I apologize in advance however...

    If iOS developers can write and provision applications to test on their own devices, why isn't it possible for someone to try to write some kind of exploitable code and run it on their device?

    It is possible -- but there's no way for a non-developer to install a developer IPA, so the exploit would not assist in jailbreaking non-jailbroken devices.

    Secondarily, even though they are writing apps for iOS, the apps they're writing are still sandboxed into the little place that Apple (if they use the Apple SDK) wants the Apps to run -- so they don't have the same privileges that some jailbreak apps would, they can't write to the root filesystem, etc. This limits their effectiveness for this purpose substantially.
    The preceding forum post has been brought to you by the letter "N" and the number 42.

    The developer can do ad-hoc distribution of their apps, this is commonly used for beta testing and was used for review copies before the AppStore properly supported gifting copies of an app for review/press purposes.

    There are different sandboxing profiles in use for the appstore apps and also for Apple's own apps. See Seatbelt - iPhone Development Wiki for details.

    Even if apps are run in this "Sandbox Space" is it not possible for someone to write just really bad code that can be made exploitable somehow? Kind of like what Geohot did with the PS3 and Other OS? (Not that I approve of what he has done in any way)
