The only other thing that may have come on the disk is an old moldy copy of outlook - at least 3 versions ago if you have the MPX200, since my 220 came with a version of outlook 2000. (outllook XP and 2003 now being out since then).
Activesync you can get from
www.pocketpc.com - make sure you download ver 3.8 NOT 4.x
Otherwise they put the usual crud like Earthlink signup, pdf version of the manual, IE mobile links on there. Maybe one of the Microsoft game packs reduced to 3 levels only. But even then, they were never good games - glorified pong if you ask me.
BTW, MPX200 has no OS upgrade, I think they may have updated the ROM once or twice on the AT&T network. If the unit is unlocked I know there were Asian ROMs with "worldwide english" but you are on your own there, not sure what hey "fixed" or changed.
The SMT5600 disk may provide you that same moldy Outlook version, but most of the applications are probablky either set by the carrier or by the unit itself, if public then they are probably pretty basic stuff.
