iOS 4 Update

iOS 4 is supposed to ship out sometimes today. This new iPhone OS will bring many new features to the iPhone, including multitasking, folders, and more.

Although the Dev Team has confirmed that a jailbreak and an unlock will be released for iOS 4, it is safe to hold off on the update for a few days if you really rely on your jailbreak/unlock.

iOS 4 will be compatible with the iPhone 4, iPhone 3GS, and iPhone 3G. Not all features will be compatible with all devices. For example, multitasking is available only with iPhone 4 and iPhone 3GS.

    Yay! First 2 comment! Well cant wait for tha unlock! Sad thing is i have 2 wait another couple dayz. I figured since they had tha unlock for months, it would come out ‘when’ 4 came out. Well guess more waitn is required. Is tha unlock gonna b via cydia?

    Is iOS4 GM on torrents not the final version coming today that’s already been jailbroken?

  • Eric

    Yeah, the GM that’s been floating around is the FINAL version that iTunes released to day… which makes me wonder why there’s no jail break besides 3gs and touch 2g.

    @Lucas no, Gold Master was version for developers to allow them get their apps ready for iOS 4, today’s version is final.

  • Eric


    Same version as the torrent, same filesize too. there’s no difference.

    IOS4 was just released

  • Lucas

    Thanks, Eric. I was thinking you could verify it by the size/release#. So I should not worry about restoring to the new one then. I guess I don’t understand why they’re saying there’s only a JB for those two models either. Weird.
