The Apple iPhone 4 16GB White - Refurbished on 3

The 3 Apple iPhone 4 not only sports a striking new design - it's also one of the most advanced smartphones available today. A significant upgrade to the 3GS - the iPhone 4 features a gorgeous retina display, hd video recording and an incredibly intuitive and simple to use interface.

Unlike the curvy 3GS, the iPhone 4 has a stylishly industrial look about it - which adds to its professional and solid feel. It's also one of the thinnest smartphones around, at a mere 9.3mm. However, the high resolution retina display is without doubt the highlight of this model - and makes playing games, watching videos and browsing the internet better than ever.

The iPhone 4 boasts two cameras. One is an impressive 5 megapixel camera with LED flash that can also record videos in HD, whilst the other is a forwards-facing camera that provides you with FaceTime. FaceTime lets you make video calls at the touch of a button. You can even switch between the front and back camera, making it even easier to share an experience with friends. With the forwards-facing camera, taking a picture of yourself is effortless, allowing you to frame a shot without scrambling for the shutter button.

Life is busy, and the iPhone 4 recognises this. Pause an application to switch to another, and when you're ready, switch back! You can carry straight on, no hassle, no waiting for the app to reload! You can listen to your own music whilst browsing the web or playing games, check your Facebook profile whilst composing an email, and switch between multiple open web pages effortlessly. With over 200,000 apps available to download, the multitasking power of the iPhone 4 really comes into its own, and will revolutionise the way you use your mobile for good.

The Three Apple iPhone 4 is a significant upgrade to the highly successful 3GS - combining exciting new features with a sleek and sophisticated redesign, and retaining all the usability and creativity we've come to expect from Apple devices.
