Mobile's day out

The first mobile phones to be loaded with Google's Android software for mobile phones have gone on show.

About a dozen companies such as ARM, Texas Instruments and Qualcomm showed off prototype handsets at the annual Mobile World Congress in Barcelona.

The free software system was launched in November 2007 and is being developed by an alliance of more than 30 companies including Google.

The first Android-enabled phone is expected to go on sale later this year.

Nokia has launched navigation tools designed to make the paper street map obsolete for pedestrians.

The firm's next generation of digital maps gives real-time walking directions on the mobile phone screen, just like sat-nav systems which guide drivers.

"Nokia is taking navigation services out of the car so it can always be with you," said Olli-Pekka Kallasvuo, president and CEO of the firm.

"Struggling with oversized paper maps will become a thing of the past."
