T-Mobile gets German court to ban VoIP software

T-Mobile in Germany has taken VoIP company Sipgate to court, complaining that Sipgate's software only works on 'jailbroken' (unlocked) iPhones. The Higher Regional Court in Hamburg agreed that Sipgate makes use of "unfair business practices" because unlocking the iPhone is a breach of T-Mobile's contract terms, which means Sipgate can't be used in Germany. The ban does not apply in other countries. [Source: TheRegister.co.uk]
