Apple has released to developers its iOS 5.1 beta, which is intended to bring several bug fixes to users. However, tech whizzes have already spotted some code within the release that points to several new Apple products that may be coming, specifically the next-generation Apple TV, the next iPhone and two new iPad models.

Developers found references to a new Apple TV which according to 9To5Mac ^[1] could feature the A5 chip found inside the iPad 2 and iPhone 4S and allow 1080p playback from the device.

They also found references to two new iPads—one which is expected in March or April next year and another believed to be a Sprint-compatible version of Apple’s tablet.

The third unreleased product reference found by developers in iOS 5.1 is for the next-generation iPhone, which is coded as iPhone 5,1. Since the iPhone 4S is referenced as  4,1 in Apple’s code, the jump from 4,1 to 5,1 indicates that major internal changes are coming. And supposedly manufacturers have already started making a 4-inch screen for the next gen iPhone, so it might be very different on the outside, as well.
