There is a protocol for this (UMA), however few operators as yet support
it.
T-Mobile offer a webnwalk tarrif (unlimited data access for a fixed
monthly fee), but they are are going to (if not already) block VoIP
calls - they've realised that users are using VoIP (probably Skype) and
not making GSM voice calls - and the voice revenue is declining.
They block VoIP and IM, supposedly to protect their users from a poor
quality experience. Of course, it's really to protect their voice and
SMS revenues.
