Apple's Phil Schiller has announced that the iPod touch is now the world's most popular portable gaming device, according to Apple statistics.
"Not only is it the most popular music player in the world, but we're excited to announce it's now also the most popular portable game player in the world," said Schiller.
Apple also revealed that over 68 million users are signed up to its Gamecentre network, which has been updated to feature friends' photos, friend recommendations and achievement points.
Apple also revealed that it had paid out over $3 billion to App Store developers, with 18 billion apps having been downloaded in total. Apps are currently downloaded at the rate of 1 billion a month.
The update was announced at the ongoing event in Cupertino, where the previously leaked iPhone 4S is likely to be confirmed.
The current iPhone 4 represents over half of all iPhone units ever sold, said new CEO Tim Cook, and iPhone now constitutes 5 per cent of the global handset market.
