.Net Compact Framework - Included in BSP's

Hello...

I have a customer asking me what version of .net compact framework is included in the BSP for an MC75a - version 3.5 is included, but Microsoft is always putting updates and patches in, so there are different "versions" of .net compact framework 3.5.

Any thoughts or suggestions of how to find this?  Also, I don't have a MC75a to look at to try to find this on my own, IF there is a way to do so...

Thanks...
