get unlocked phone and do what you want
I just bought a nokia E71, understand not iPhone, but I can make calls using VOIP app Fring to/from gchat and skype, not the greatest on edge network, but on 3G/Wifi is as good as a regular cell call. I can also do video chat as well, not as great but proof of concept is there. Go register yourself an IMEI number of a cheap goPhone, buy the 15$ unlimited data plan and then put your sim in a high powered unlocked phone and totally avoid paying the 30 dollar fee that they would charge you if only they knew what phone you had. At least most of you aren't using a Verizon phone, all the capability of the phone taken out because Verizon puts their own OS over the top of the manufacturer.
