This is the first time the iPhone has changed its screen size since the original 2G iPhone launched way back in September 2007. Apple has kept the screen size of its iPhones and iPod Touches the same for continuity reasons all this time, so it will be interesting to see what effect the new screen size has on the iPhone 5's apps and OS. Take a look at the iPhone 5 price in UK and iPhone 5 Advisor too.

Here are the confirmed iPhone 5 specs and features:

iPhone 5 specs and features

iPhone 5 screen:

The new iPhone 5 will feature a screen that is half-an-inch bigger than its predecessors. That means that the iPhone 5 will have an impressive 4-inch Retina display of 326ppi and an 1136x640 resolution.

Apple has said that older apps designed for the 3.5-inch screen will work in just the same way on the iPhone 5. Apps will just be centralised and the extra screen space on the sides will be greyed out.

iPhone 5 processor:

As predicted, Apple has upgraded the processor in the iPhone 5. What might come as a bit of a surprise is just how much they've updated it. The new A6 chip found in the iPhone 5 has a 2x faster CPU and a 2x faster graphics. All this in a chip that is 22% smaller. Apple claims that the new chip offers 2x better performance across the board.

iPhone 5 with iOS 6:

A lot has been made of iOS 6 and rightly so, it's going to bring a whole new style of cloud computing to Apple devices. Take a look at our iOS 6 preview for a more complete look at it.

  • Next is Mail. Added a feature called VIPs, which lets you mark people as VIPs and all message from them in the inbox are collected in one place.
  • Passbook is next. This is the way to collect all your passes in one place: movie tickets, airline boarding pass, coupon, store card with a balance, ticket for a concert, a ticket for a baseball game. Evening Boarding pass automatically appears on the lockscreen when you're nearby.
  • Shared photo streams is next. Create a photo stream and when you add photos to it it shares them to your friends.

iPhone 5 4G:

It's got 4G!!! The iPhone 5 has all of the iPhone 4's connectivity that includes GPRS, EDGE, EV-DO, HSPA, and added HSPA+, DC-HSDPA. The main addition to this is LTE.

Other features include a camera that is backside illuminated, has a hybrid IR filter, a five-element lens, and a fast f/2.4 aperture.

All of that and it is now 25% smaller that takes photos 40% faster. Impressive.
