Nokia says it has filed a complaint against Apple with the Federal District Court in the Western District of Wisconsin. It's alleging that Apple iPhone and iPad 3G products infringe five Nokia patents that relate to enhanced speech and data transmission, using positioning data and innovations in antenna configuration.

Paul Melin, Nokia's General Manager of Patent Licensing, said "Nokia has been the leading developer of many key technologies in mobile devices. We have taken this step to protect the results of our pioneering development and to put an end to continued unlawful use of Nokia's innovation."

The European Commission has implemented new rules for high-speed mobile internet services. EU members that release 800MHz frequencies as part of the 'digital dividend' resulting from the switchover from analogue to digital television broadcasting are now required to make the frequencies available for wireless broadband applications such as LTE or WiMAX.

Seven more countries have backed the EU’s campaign to equip new cars with a mobile-based emergency call device that would automatically phone for help in the event of an accident.

Belgium, Bulgaria, Denmark, Luxemburg, Malta, Poland and Romania have all signed a non-binding agreement with the European Commission to deploy eCall, the proposed in-car emergency call system.

The global market for preloaded software on mobile phones is likely to more than double from 2008 to 2014, according to new figures from iSuppli Corp. It says this market will expand to $7.7 billion (£5.25 billion) in 2014, up from $3.3 billion in 2008. At the same time, worldwide shipments of smartphones are set to rise from 161.1 million units in 2008 to 497.4 million in 2014.

Preloaded software - applications that are already installed in mobile phones when they're bought by consumers – is paid for by the equipment manufacturer, which either buys it from a third party or develops it in-house.
