    Why is there a dramatic size difference in the actual file size of the new iOS 5.1 when updating it via iTunes account vs updating via the actual device wirelessly?

    What I mean is this:

    To update via iTunes - the file size is showing as 803MB

    To update via the device (iPhone or iPad) wirelessly w/o logging into iTunes - the file size is showing as 189MB

    ?????

    Anyone know the answer?? The above is definitely the file sizes I am seeing as noted for ONLY the 5.1 iOS update d/l.

    The iTunes version is the complete firmware required for a full restore. The version directly downloaded on the device is essentially just the parts of the firmware that are changed between the current installed version and the update.
