The revamped gadget has a stainless steel case, integrated antenna, improved display and is 24{6060b2de664e4eaa3e7b7e86961ce2c4bbd7a29b6c1097abf8257a4e5b07383e} thinner than the most recent version. Apple boss Steve Jobs said the redesign was the “biggest leap” it had taken since the launch of the first iPhone. But analysts said the phone’s popularity could be dented by Apple’s strict control over what owners can do with their gadget. The gadget was revealed during the keynote speech at Apple’s Worldwide Developers Conference in San Francisco. The device will go on sale on 24 June. The US price for the 32GB model is around £206 and £137 for the 16GB model. Apple said prices might be affected by contract conditions. Apple was forced to ask conference goers to stop using wi-fi to ensure that some demos of new features went smoothly. Mr Jobs said the 570 wi-fi hotspots in the room made it impossible to carry out some demos. According to research firm Gartner, Apple’s iPhone now has around 15{6060b2de664e4eaa3e7b7e86961ce2c4bbd7a29b6c1097abf8257a4e5b07383e} of the smartphone market, behind Blackberry and market-leader Symbian. Despite Apple’s position in the smartphone market, analysts warn of stiffer competition especially from nearby neighbours Google. “The rise of Google Android over the last two years has been phenomenal and is allowing manufacturers to create appealing alterntives to the iPhone; critically at cheaper prices,” said Adam Leach, principal analyst at Ovum. “These handsets are more than just iPhone clones,” he said. “The risk to Apple is that these devices offer greater freedom with available content and may prove more appealing if it offers the right user and developers experience, than a device with Apple approved content only.” Credit: Reuters/BBC/APD/de-world.de
