Apple has begun shipping a souped-up so-called "iPhone 4S" to games and app developers, in preparation for the forthcoming launch of the new iPhone 5.
A select few games devs have received the new Apple iPhone, to help them prepare the best titles possible for the iPhone 5 launch.
A5 chip in iPhone
9to5Mac reports that the new handsets feature Apple's super-nippy A5 chip, allowing developers to create the fastest and best-looking mobile phone games yet possible.
9to5Mac's source claims that the "iPhone 4S" is almost identical to the current iPhone 4, apart from the inclusion of the newer, faster processor.
The iPhone 5 is rumoured to be launching later this year, with no official word, as yet, from Apple.
