Three have announced their iPhone tariffs, which are the cheapest of all the major operators.

You can get an iPhone 4 free on a £45 tariff which will get you a 16GB iPhone 4, 2000 minutes, 5,000 texts and 5000 3-to-3 minutes.

The same contract as above is available with a 32GB iPhone 4, which will cost you £89 up front.

When you consider that the lowest price contract where you can get an iPhone free on the other major networks is £60 a month , you'd have to say the Three deal is a good one.

They also offer some better value tariffs which involve paying more the iPhone up front. Additionally, Three announced yesterday that they will be offering micro-SIM only deals, which you can read about by clicking here.
