    I have the older firmware, and my menus and especially contacts are quite sluggish. I wanted to see if updating the firmware would fix it. It doesn't update automatically, do I have to 'restore' the phone through iTunes for it to work? Would I lose anything, or would all my apps/pics/music be re-added on the subsequent sync?


    Thanks...

    You can't have the old firmware. There's only one.

    What older firmware? 2.0.0? That is the current firmware version.

    As new firmware versions are released, they will be available through iTunes, and installable via the "update" button under iPhone's preferences in iTunes.

    There's two different firmware builds fo 2.0 for the 3G. One that shipped on the phones and slightly newer build that downloads from Apple.

    To get the new build, you have to do a restore in iTunes. It'll download the newer build and restore it onto the iPhone. Make sure to do a sync so you'll have a current backup before you do the restore.
