October 15, 2011, 8:15 AM — The iPhone 4S will launch on Friday 14 October and is available with three storage capacities - 16GB, 32GB and 64GB - and comes in two colours, black and white. When it comes to how much you'll have to pay and getting your hands on one, things start to get a bit more complicated.
Macworld has put together this comprehensive buying guide for the iPhone 4S, so if you're planning to take the plunge then read on to find out everything you'll need to know.
iPhone 4S specs and features
At a glance, the iPhone 4S looks similar to the iPhone 4, but on the inside is a very different beast. There's a dual-core A5 processor, the same seen in the iPad 2; dual-core graphics, offering up to seven times faster performance; 1GB of RAM, twice as much as in th iPhone 4; and the camera is 8MP (compared to 5MP in the iPhone 4) and shoots video at 1080p (compared to 720p).
In terms of software and services, it'll run on iOS 5, though only the iPhone 4S will be able to support the Siri personal assistant. It also supports iCloud, giving you online storage and backup for all of your important documents.
Pre-ordering an iPhone 4S
So now you've made up your mind that you want one, here's how to go about getting your hands on the iPhone 4S. Though launch day is a few days away you can pre-order the device through Apple and several (but not all) of the major UK mobile networks.
Vodafone, T-Mobile and Three will all let you pre-order an iPhone 4S through their respective websites (though Three will initially only sell 16GB models through its stores), whereas Orange requires you to phone its call centres. O2 has taken a slightly different tack, opting to make its stock available only to existing O2 customers who turn up at one of its stores on launch day.
SIM-free iPhone 4S
If you want to go SIM-free, you'll have to go through Apple. It'll cost you £499 for a 16GB handset, £599 for the 32GB version and £699 for a 64GB model. You can pre-order online, though Apple's site is currently quoting a wait of one to two weeks, meaning that you probably won't get one on launch day.
