Smartphone updates explained  Periodically, smartphone makers issue software updates for their phones' operating systems. These can be sent out automatically over the air through the network, or will require the smartphone owner to download them manually. Updates for smartphones generally add great new features and are also used to fix any faults that might have been present with existing versions. Google is perhaps the most regular issuer of operating system updates, often putting out several new iterations of its Android platform every year. By contrast, Apple usually sends out just one new version each year for the iPhone. Check out and compare offers on Android phones at our dedicated Android page.

For contracts they are supplied free or at a heavily discounted price. However, on pay as you go packages or if buying unlocked, the latest smartphones can cost up to 600. This can be quite a steep sum to pay for a handset for most average shoppers, and as a result many smartphone buyers tend to choose a monthly contract option when picking up a newer, more expensive model. These are designed to subsidise the cost of the phone and usually run over a period of between 18 and 24 months, so youre essentially spreading out the cost of your mobile over a longer period. Most monthly smartphone contract prices range from 20 to 40, with varying texts, talk-time and data allowances. In order to make the most of your handset, Uswitch recommends picking a contract that offers a generous web usage limit. This will enable you browse the web, download more apps and stream videos and music without incurring extra charges. Compare all the latest phones at Uswitch now.
