Hmmmm, I did nothing special to setup more than one partnership, my laptop
actually has 3 as I have my wife's iPaq on there as well........
If you plug in your phone you should get a popup asking if you want to
create a partnership or run as guest, if you create a partnership it should
all work ok.
The only thing I have done on the phone is use RJV Registry Tweaks
(
www.airfagev.com) to change the phones name from the defaul C500 one.
Try that it may help.
The other thing to try is to delete all of your partnerships on the pc (open
up ActiveSync then click File Mobile Device, select the device then click
File / Delete Mobile Partnership.) do it for all the devices you have
Then try re partnering the devices with the pc. My iPaq was the first device
connected.
If that doesnt help let me know.... Oh and check your using the latest ver
of ActiveSync
