    just plug the iPhone in and choose restore
    iTunes will handle it

    keep in mind that if you ever want to have the chance to unlock, do NOT upgrade
    but it sounds like you don't
    so you'll be ok

    But you will lose 500 MB of storage from the partition that gets installed when you JB. Restore is the only way to get it back...

    Restore but the best way is to go back into DFU mode and restore it with a virgin IPSW.

    I am sure it is listed somewhere in here but can you tell me or direct me to how I restore in DFU mode with what you call a "virgin" ipsw?

    Google it next time and you won't have to wait for someone to tell you. ;)

    And "virgin" in this case just means stock. You can just use itunes for that.

    Wrong on your part! :)

    All Apple firmware updates completely wipes the device to update. The 2.2.1 update has been confirmed at ~ 260MB, which is a complete build, not just a simple update.

    Wrong on YOUR part. An Apple update may re-write the entire OS but, it doesn't touch the "mobile" folder so you don't lose your music, videos and settings.

    Restore=erase iPhone and install 2.2.1
    Update=archive and install (keeping user prefs and music)

    As a general rule of thumb it is best to restore and setup as new rather then restore from backup. It is possible for jailbroken files to be restored without someone knowing. I have seen it personally.

    The only jailbroken files it can restore from a backup are files in the user's folder, such as preferences. If you wanna be clear, you must un-install various preference-hacks before restoring. The kind of hacks I'm talking about are: Emoji or Battery Percentage... These are simple plist edits in the mobile/Library/Preferences folder which DO get backed up.

    Ok, fair enough, I stand slightly corrected. :) If however you want to go to unjailbroken from jailbroken, I'd advise not just updating but restoring, which will wipe everything out. :)
