Although the iPhone 4 have been on the market for a while now, it still remains to be one of the most popular and powerful smartphones and there are some great iPhone 4 deals at the moment. It was recently replaced by the iPhone 4S which has made for some major price cuts for the device recently. When the handset first launched it was quite expensive, but now a lot of the offers will give you the iPhone 4 completely free of charge.

If you are going to sign up to a new contract you need to think about it properly first. I would recommend trying to work out roughly how many minutes and text messages you use each month on average. You don't want to sign up to a new contract only to find out you needed more minutes than you thought. It is always cheaper to just get the right tariff for your needs in the first place.

Use our handy comparison table below to find the best deal for you. I would recommend one of the deals with Three as they give you the best value for money.

The iPhone 4 has a very strong and advanced set of features. It has two cameras, one intended for things like Facetime conversations or video calls and the other as the main camera. The main 5 megapixel camera can capture breathtaking images and also record HD (720P) videos at 30 frames per second with sound. The camera is also supported by an LED flash which makes taking pictures in dark places a lot easier. You will be able to share all of your pictures and videos with your friends on social networks with just the touch of a finger.

The touch screen Retina display measures 3.5 inches across and provides really sharp and crisp images. The screen also has a oleophobic coating which will help to prevent messy fingerprints. There are also features such as Wi-Fi, GPS and a digital compass which seems to have become standard features on phones over the last few years. There is also a range of digital sensors such as the gyro, ambient light, proximity and accelerometer sensors which are used by developers to enhance their apps and games. All of this is powered by the Apple A4 processor which is also used in products like the iPad and iPod Touch.

When the Apple iPhone 4 first launched in the UK it was exclusive to the O2 network. Now there are great iPhone 4 offers available on every network including TMobile, Three, Vodafone and Orange. They are all at war with each other over the price of the iPhone 4 so make sure you shop around and get the best deal for you at that time. If you are getting a new contract than just make sure it comes with everything you need so you don't end up with a huge unexpected phone bill.
