You might be able to find a feature list for WM6.1 and compare to a similar
list for WM5. This one I found with Google in five seconds:
http://www.microsoft.com/windowsmobi...n-compare.mspx
Presumably, if you're getting the ROM image from the device OEM, they'll
tell you why they think you want it.
You'll definitely need AS4.5, if you do upgrade.
