i believe the problem you have is that you have to set up DUN properly on the Q.
i am selling my treo on ebay and bought a krzr and went through this process 2x (once on the treo and once on the krzr) you should research on how to enable dun on the q which is why i suggested mark.cdmaforums.com and verizonwireless.howardforums.com.

cdma/verizon dunning is a bit more tricky than standard gsm
