Hope you got it sorted out.
I understand your need for a ipaq to communicate with your CAI 302 via the CAI Utility software.

I'm a 302/303 user.

That said when the ipaq's completely fail look into a Oudie 2 with seyoumobile.

Great device and software and you can, presently, load turnpoints into your 302 and download you flight file from your 302 with a Oudie.
It is easy upload your flight to the OLC or a contest with the Oudie.
The Oudie also logs another flight log in case your 302 file is bad for any reason.
The one thing the Oudie won't do is handle the CAI Utility. We 302 / Oudie users need to ramp up the pressure on Naviter to allow the CAI Utility to run on the Oudie and then it will be the perfect device to couple with a 302.
You can communicate the settings to a 302 with a 303 thou and this is the way I change settings in my 302 when I don't have my ipaq [ which is on life support] handy
Happy landings
