Arm vs. Arm4

[Guest]

I have written a Compact Framework app and I've built an installer for it
using EZSetup. When I run the BuildCabs batch file, .Net generates an Arm,
SH3, Arm4 and a few other versions. I've read that the only devices that
support the Compact Framework are Arm based. Because of that, the only CAB
file I've added to my installer is the Arm CAB file.

My question is, should I use the Arm4 version instead of Arm? What are the
differences between Arm and Arm4? If I only include the Arm4 CAB file will
some older devices not be able to run it? Are there speed or performance
differences between the two?

Thanks in advance.

I suppose it will clarify the situation.

Pocket PC 2000 devices which support .NETCF exist with MIPS, SH3 or ARM
processors. All subsequent Pocket PC models are ARM based.
By default the cab generation wizard creates an ARM cab for Pocket PC
2000/2002 (Windows CE 3.0 based) and ARMv4 for Pocket PC 2003 (Windows
CE.NET 4.2 based).
