Apple is famously secretive regarding new products: launching new phones, computers and whizz-bang devices on a (largely) unsuspecting public out of nowhere. All this causes a tremendous amount of excitement among tech industry watchers as people worldwide speculate, theorise and imagine just what the Cupertino-based company is really up to.

Speculation regarding the next generation of iPhone is rampant, especially now that Apple has announced iOS 6, the operating system set to power the new phone. We are pretty sure Apple is ready to launch a sixth-generation iPhone alongside iOS 6 this autumn (probably September).

Apple has launched a new iPhone in the middle of every year since 2007, slowly introducing new features like the Retina display, HD cameras and Siri to gradually ensure each model is better than the last. This encourages owners to upgrade to a new phone, gets new people leaving their contracts to choose an iPhone over another model, and prevents people from jumping ship to another platform like Android (perish the thought). Although the iPhone 4S is as damn near perfect a phone as we can think of, there’s no reason to believe Apple won’t release an even better model this year, and judging by our first look at iOS 6, the next model is going to be a stunner. So we decided to put together the definitive guide to what you can expect from the next-generation iPhone.

Welcome to the wonderful world of iPhone speculation. Trying to second-guess Apple’s every next move is an obsession of ours: we’ve scoured the patents, analysed the business deals and spent a lot of time searching through some of the more remote, and potentially reliable, sources (typically based in China and close to the manufacture of the device). There’s also we admit, a fair amount of finger in the air guesswork. But these are the features we think you can look forward to in the next generation of iPhone.
