The rumour is that Apple has started shipping few iPhone 4’s with A5 dual core processor to many Big Game Developers. This could very well the precursor to the next major iPhone version in the near future. But what makes it more intriguing is that phone shipped to developers is almost same as the iPhone 4 in terms of looks. The difference is in the processor, Memory and the 8 MP camera.
Meanwhile there are also rumors of a white iPhone with TMobile USA 3G version. But it very well could be just pictures of TMobile UK iPhone, which is more probable.
