Apple has unveiled a second generation of its iPhone, with support for faster 3G wireless networks.
The company is hoping to boost its share of the smartphone market, which is dominated by Nokia and Blackberry.
The new devices were launched by Apple boss Steve Jobs who said the phone would be "more affordable" for consumers, starting at $199 (£100).
The new iPhone also comes with GPS satellite navigation built in for location-based services.
The iPhone was first launched last year and was criticised for its support for slower 2G networks only.
Mr Jobs said the 3G iPhone was "three times faster" downloading content over a mobile network compared to the original device.
What a load of bollocks!!
iPhone my arse - It doesnt matter what the hell o2 try, they simply cannot shift them, because outside of the US, people are actually clued up about mobiles and not still living in a 2.5G past where they just bend over and let the networks rob them! BBC News Report
