Nokia made a few changes to its organisation last year – and it's reorganising again in a bid to "accelerate execution and innovation". From July, Nokia will introduce a simplified company structure for its devices and services business. There'll be three units: Mobile Solutions, Mobile Phones and Markets.

The new Mobile Solutions unit will concentrate on Symbian smartphones and MeeGo mobile computers. The Mobile Phones unit will focus on Series 40 feature phones – and the Markets unit will be responsible for Nokia's 'go-to-market' activities.

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."

At Nokia's AGM today, company CEO Olli-Pekka Kallasvuo told shareholders that Nokia had built a solid foundation for future success.

He said "By combining services with devices, Nokia is in a stronger position to grow and create more value for our shareholders. We still have plenty of work to do, but we have built a solid foundation. We believe in our strategy."

Mr Kallasvuo also said Nokia is planning to introduce a new generation of devices this year that he expects will help close the gap with high-end smartphone competitors.

Microsoft and Nokia have launched the first application that's been created from the partnership announced last August. It's called Microsoft Communicator Mobile and is a business-focussed communications client for selected Symbian-based Nokia Eseries smartphones.

Communicator Mobile enables users to see their colleagues’ availability from the contacts application. Users can then click to communicate with colleagues using their preferred method, from instant messaging and email to texting or making a phone call.

This new application is available to download for the Nokia E72 and Nokia E52. The two companies plan to pre-install Communicator Mobile on select Nokia smartphones in the future, with support for additional devices also planned.

This week's edition of The Fonecast is full of big names. HP acquires Palm, HTC and Microsoft do a deal over Android, Apple sells a million iPads - and handset sales show some dramatic increases.
