Apple's iPhone launch event: what to expect

In a matter of hours, Apple CEO Tim Cook will take to the stage and months of rumour, speculation and basically just having a stab in the dark will come to a head: the iPhone 5S will be official.

But that's not all! We're expecting a host of announcements from Cupertino later today, and we'll be covering them all in real time both here on the site and over on Twitter.

Join us right here from 10 am PT / 6 pm BST / 7 pm Berlin time / 4 am Wed AEST for all the Apple-flavoured fun, where we'll be dissecting what Big Cook will be talking about, whether fingerprint tech will be popping up, whether a new cheaper iPhone will be coming and other general frippery.

You can even come a bit earlier and witness as TechRadar attempts to defy the Wi-Fi gods in Apple's fancy new Berlin store to bring your some pre-game action.

Ready for new iPhones? We are.

iPhone 5S

The big daddy. The new iPhone. Or the only-slightly-different-to-the-old-iPhone if the details we've seen in the most recent rumours turn out to be true.

Expect a souped-up camera, a better processor and iOS 7 on board.

iPhone 5C

With a simultaneous official event taking place in Beijing and the spotty dotty rainbow of an invite to boot, we won't be at all surprised if Tim Cook's first "One More Thing" moment turns out to be a cheap iPhone.

We've seen cases, components and pics galore - but we're still not really sure what the thing will be called. So that's exciting.

An iOS 7 release date

The iOS 7 software went out to developers in beta form back in June - if Apple doesn't announce an imminent release of the OS to iPhones, iPads and iPod Touches today, we'll eat our collective hat.

An iTunes Radio release date

We don't expect any countries other than the US to get an iTunes Radio release date today, but the North Americans among us should find out when the Apple-flavoured music streaming service will be hitting your devices.

An OS X Mavericks release date

The new version of OS X was announced back at WWDC 2013 and has been in developer preview ever since.

Will Apple today tell us when we'll see the OS X Mavericks software hit Macs the world over? Here's hoping. Anything to get us out of Mavericks and into something with a better name is all right by us.

A wildcard One More Thing?

What if the One More Thing isn't an iPhone 5C? This time last year, Apple knocked us all for six when it announced the iPad 4 alongside the iPad mini. Perhaps we're in for something a little more surprising this year - an iWatch? An iTV? The new Mac Pro?

One thing's for sure: with Apple, you can never be sure of anything.
