    If you upgrade you will loose nearly all your jailbreakon apps and tweaks.

    Best way to upgrade is to download the 3.1.2 ipsw file and then shift+restore to it.

    appstore app data will be saved within your backup in itunes, after upgrading press restore from backup, all your data should be back such as notes, contacts, app data. I have no information for cydia apps tho.

    You can save a copy of stuff like winterboard themes (/stash/Themes/, I think) via SSH and then recopy them back after the upgrade.

    You can't unless you backed up your 3.1.3 SHSHs. Why does it matter if you on 3.1.3 or 3.1.2? There both jailbroken. If you need it for an unlock 3.1.3 isn't unlocked.

    Any specific reason for 3.1.2 ?
    Spirit JB works for any iphone. You can just upgrade to 3.1.3 and happily JB it. Save all your troubles.

    Save games?
    1. sync/backup with iTunes
    2. shift restore with latest firmware
    Download from http://www.felixbruns.de/iPod/firmware/

    3. after restore, JB it first and installed necessary apps from cydia.
    4. restore your last backup with iTunes

    Backup/Restore Cydia Apps ?
    1. Install Rock
    2. Register RockID
    3. Save your app list to Rock server
    4. Restore your iphone
    5. After JB, restore backup from Rock

    There are many alternatives: appbackup, aptbackup, pkgbackup.
