The iPhone 4 is far more than just a mobile phone, in fact most users say that phoning is probably the last thing they use it for! iPhone 4 incorporates a very usable web browser (Safari) and email program, the eternally useful Google maps with a built in GPS so you can see where you are on the map, an iPod to play music and videos, a camera with flash and even an HD video camera, and it runs over 350,000 apps covering everything from games to learning languages to weather forecasts. With all that packed into one small device, it needs to be easy to use - and it is. iPhone 4 has a very high quality touchscreen display with probably the best thought out user interface of any consumer device ever. It's powerful and sophisticated but it's very easy and even enjoyable to use.
The iPhone 4 is without a doubt a great phone. Most people who own one love it and wouldn't change to any other. The iPhone 4 has come in for a lot of criticism however - firstly for it's antenna problem and secondly for it's battery life. If you use it heavily it will eat through it's battery in a few hours, however this is really just a consequence of it's power and complexity and really isn't a problem provided you have access to either a mains socket or a USB socket to recharge it. The antenna problem is also not a problem as long as you know how to hold the phone so as not to bridge the antenna, or if you use (as most people do) a case or cover that prevents you from doing this, it's absolutely no problem at all.
There are two ways to buy an iPhone 4 - as part of a contract with a network such as Vodafone or O2 (either directly from the network or through as reseller such as Carphone Warehouse, Phones 4 U or Dial A Phone) or to buy it outright and buy your phone service/SIM card separately. Amazon and eBay are good places to find cheap deals on iPhone 4s for outright purchase. We have put together an iPhone 4 price comparison page checking prices from all these sources to find the best deals for you.
Secondhand can be an attractive option, saving you the initial depreciation that happens as soon as you open the box, and if you buy a fairly new secondhand one, all the manufacturer's warranty will still be in place so you will be fully covered in the event of any faults. If you're prepared to go slightly older, you can often pick up some real bargains with last year's model going for a fraction of it's original price. eBay is of course one of the best places to find secondhand iPhone 4 bargains and we have created a page that searches eBay for you to find the best deals. Our unique filtering system trawls through the eBay database selecting only the most relevant offers and best deals to save you time.

In the USA, the iPhone 4 comes in two different versions - the original AT&T iPhone 4 and the new (February 2011) Verizon version of the iPhone 4.These phones have different chipsets inside because of the different technologies used by these two carriers (Verizon use CDMA and AT&T use GSM) and are therefore not interchangeable. Be careful if you import an iPhone from the US!
