sipgate

At the request of T-Mobile, the Higher Regional Court in Hamburg has banned VoIP app Sipgate from being sold for iPhones in Germany. The app, which oddly enough is available through the App Store, lets users make phone calls using T-Mobile's Wi-Fi network that are both less expensive and don't include roaming charges.

We knew that phone carriers aren't generally big fans of VoIP services in general, but T-Mobile Germany is taking it to the next level. Apparently they've decided that sipgate's flagship VoIP software is encouraging their users to jailbreak their iPhones and use VoIP software to place calls, both which they say is against T-Mobile's user contracts. The solution? T-Mobile has asked them to cease and desist offering their software entirely.
