An interesting tidbit from a report found by Tom Schouteden at the Sipcat VoIP Blog suggests that by 2012, SIP over wifi will be dwarfed by SIP over 3G mobile phone networks. Specifically, they are predicting 250 million users on 3G and only 100 million users on WiFi.
Seems kind of nonsensical today, given that most 3G operators have rules that make the use of SIP impractical or against the usage policy. However, if the operators go away from a circuit-switched model and go purely towards a data-only model, I could see this happening fairly easily. It's be transparent to the end users that way. The fact the communication traverses an IP network or a circuit-switched network is an irrelevant distinction for the vast majority of people.

we are at a point where we clearly need new vocabluary to distiguish between third party cost saving VOIP services that sit on top of IP links; and a switch from circuit switch to packet switch technology by major telecoms.
i do not consider the switch by major telecoms to have anything in common with the products i use to save money on phone calls.
i consider myself at this point a fan of ‘toll bypass’ services as opposed to ‘traditional phone’ services. the underlying technology is much less of a concern.
No arguments on that.
Telecom marketplaces rarely provide a fully interactive environment where buyers can challenge sellers to provide their best price.
Moreover, buyers with small buying capacity can rarely benefit from discounted prices based on bulk orders, specially in the telecom minute business.
