T-Mobile, Truphone tussle

It seems T-Mobile is refusing to interconnect with Truphone, a U.K.-based start-up with a VoIP client that enables its end users to make cheap voice calls using a dual-mode phone. T-Mobile has reportedly created a policy not to connect to low-cost calling services, especially if the services or service providers offer a client like Truphone's which allows end users to send free SMS messages and make calls over 3G networks.
