iPhone 6

Apple spent a significant amount of its WWDC 2014 keynote focusing on iOS 8, which takes the flat iOS 7 design and only rounds it out with new features.

That means instead of a dramatic redesign, you can expect this year's mobile operating system update to tie everything together with the overarching theme of "convergence."

iOS 8 will feature tighter Mac integration while loosening the restrictions on Apple's Touch ID fingerprint sensor. New software kits are also bringing once fragmented security and health gadgets together.

While there was no mention of an iPhone 6 or an iWatch at this year's WWDC, Apple seems to be setting the stage for a new wearable device by the time iOS 8 is ready for public release.

The new iPhone could be one of the most pivotal devices in the Cupertino brand's history - with the iPhone 5S andiPhone 5C simple updates to previous models, there's a lot of pressure heaped on the iPhone 6.

·         What iOS 8 tells us about the iPhone 6

Some of you might have been expecting the iPhone 6 to have debuted in 2013, but given the iPhone's history - from the 3G onwards, there's always been a half-step S model before the next numbered iPhone - we were never going to get the 6 until 2014. In fact, it will technically be the iPhone 8 when it finally launches... but hey, who's counting these days?

One thing is for sure, with the Samsung Galaxy S5, Sony Xperia Z2 andHTC One M8 now out in wild, Apple needs to be on its game with the new iPhone - and many believe a bigger screen is simply a must.

iPhone 6 release date

The iPhone 6 release date will be in 2014 and it's looking increasingly likely that we'll see it in September, which would fit in nicely with the rollout of the newly announced iOS 8.

Apple has launched the last few iPhones at a special event in September, so the smart money has always been on September 2014 for the iPhone 6's arrival.

Not to mention the fact that according to ifun.de Apple is restricting holidays during September for employees at German Apple Stores, which strongly suggests a new hardware launch then.
