I don\'t know what you have done to this point but what I did:
Setup a profile in network settings, no username, no password, with 1xRTT network and phone no #777, init string of ATZ, speed of 115200 with defaults for everything else.
After connecting phone to zaurus, use the appropriate profile from the network connection icon and then connect. Just blow past the username and password prompts.
I\'m not sure but I don\'t think you really need the ipk unless you have the hi-speed service. hth.
