ActiveSync versions for different OSs - compatibility?

I have Activesync 3.8 supporting my HP iPAQ POCKET PC running Windows Mobile
2003 Second Edition.
I just got a Cingular 2125 Smartphone running Windows Mobile 2005
SMARTPHONE. including Activesync 4.1
When I tried to install Activesync 4.1 it insisted in overwriting my version
3.8.

Several questions since I thought Windows Mobile 2003 Second Edition was NOT
supported by Activesync 4.1.

Can both a Pocket PC and Smartphone run off the same Activesync?
Can I run both OSs (v2003SE and v2005) from one Activesync?
If so, which version do I use?
If not, how do I install both verisons of Activesync on one hard drive?

Thank you.

WM2003SE is supported by ActiveSync 4.1 - it basically uses the engine
from ActiveSync 3.8 for devices running WM2003SE or earlier, and the
new engine for WM5 devices.

Yes.

Yes.

You must use ActiveSync 4.0 or later to synchronize with any Windows
Mobile 5 device.
