API to retrieve hardware and PRL?

[thetao]

Does anybody know if there is a standard, published way (or at least a limited number of ways) to retrieve device hardware information on a Windows Mobile device? I'm thinking of the ROM version, Radio version, and the PRL version (on CDMA devices). I am mostly familiar with HTC devices, and am not sure if every WM device has a Device Information program or an equivalent of ##RTN# (on a Sprint WM device).

Thanks for any ideas,

Todd
