  • Apparently, just a bunch of bug fixes

  • Mr. K

    I hope this doesn’t patch up some of the discovered exploits. Doubt it but still possible.

      Apple keep tracking using Diagnostic reports which generated automatically in the phone. And, they fix immediately if they found something

  • Kwopau

    I think I’ll stick to iOS 5.1 for now.

    4S jailbroken on 5.0.1 still. Boom!

  • pakaku

    But does it improve that god-forsaken lag whenever I try to use the keyboard or magnifying glass on my iPhone 4? Or is it just me? Holy sh*t, if 5.1 or 5.1.1 don’t fix it, I may just try to downgrade back to 4.0 if possible.

  • mkimid

    Actually, some more updates will be announced till iOS 6. And, many securities holes will be fixed and closed. I am interesting what this updates will affects on the currently founds by pod2G

    5.1.1 shows Apple knows about an unreleased technique to downgrade A5 devices to 5.0.1 with saved blobs (but left it alone..hmm)

    Sounds like good news to me

  • jdw

    Does anyone know a site that I can download the new iPad 5.1.1 firmware from that supports resuming? I have an unreliable internet connection.

    • avik

      • jdw
