I’ve written a review of iOS 6, the latest free upgrade for Apple’s iPhones, iPads and iPod touches. Is it good? Yes, but the newer your hardware the better it is.

the older the kit the less of iOS 6 you actually get. Some of the big features – Siri, turn-by-turn navigation, panoramic photos and FaceTime over 3G – aren’t available for the iPhone 3GS or iPhone 4.

The 3GS doesn’t even get the offline reading list feature, and Siri’s not available for the iPad 2.

Is it worth the upgrade? We’ve installed iOS across multiple iOS devices: an iPhone 4, an iPhone 4S, an iPad 2 and a new iPad (that latter one courtesy of Vodafone) to find out.

As we discovered, even when you don’t get all the new features, there are still enough improvements to make the jump worthwhile.

On a tangent, spending any time whatsoever with a new iPad makes older iPads feel ancient. That retina display is a thing of beauty. Weight-adding, battery-killing beauty, but beauty nevertheless. The more I use it the more I think I’ll barricade myself in when Vodafone comes to take it back again.
