Just throw a cd-r in ur drive. Put this version,
activesync 3.8 on it. Thats about all they will use.
The cd does come with some trial apps, so u can put some of those on the cd. Resco File Explorer, monopoly, etc.
Then just lie to them and say its the x50 cd. Afterall i never really use the cd, everything u need is on the net already, except outlook, which i dont use.
