hey. im makin a new thread juss to make it simple.

here are the facts. im using a verizon treo 600 on the verizon network. im on a pay as you go data plan (15 cents/1k).

here are my questions:
1. is there any way to disable the data plan? i begged the service reps to not give me it but they did
2. if i dial out QNC will it take away from my minutes or charge me under my pay as i go data plan?
3. is it possible to change the ESN? i heard that you can do it and change it to another phone that supports free EMU (w/e it is) under the National Access plan im on

thanks in advance for these questions
