To get 3-4mb without needing a new .cab... you can edit the registry some more =)

1. HKEY-LOCAL-MACHINE
2. software
3. arcsoft
4. arcsoft mms ua
5. config
7. ui
8. sizelimit
Wap2SendLimit3 = "4194304"


AND...


1. HKEY-LOCAL-MACHINE
2. software
3. arcsoft
4. arcsoft mms ua
5. config
7. mm1
8. MMSCSettings
9. SampleMMSC

WAP2SendDefaultSize = "4194304"

This sets the third setting (which is pre-selected when you install the .cab I linked to) to 4mb and ups the send limit as well.
You can do whatever size you want, just put in a bigger number =)
