The cheaper iPhone 5 costs £300, £200 and £50 on each of the three tariffs.
The 32GB model iPhone 5 costs £375, £275 and £125 on each tariff respectively.
The most expensive iPhone 5 costs £450, £3501and £200 on each of the three tariffs.
There are also a bunch of 12 month options on £30 and £40 a month tariffs with Tesco Mobile. These are rather costly options though, since the basic 16GB handset will cost you £400 and £300 upfront.
Tesco confirms the handset will be available on pay as you go at a later date.
Three has by far the most exciting handset pricing. The guy in the 3 Store we went to explained the great pricing is a result of the network shifting so many iPhone 4S handsets. What's more, Three is keeping things simple and there are just two 24 month contracts to choose from.
The unlimited internet 500 tariff gives you 500 minutes, 5,000 texts and unlimited data, while The One Plan offers up 2,000 minutes plus 5,000 Three to Three minutes, 5,000 texts and all-you-can-eat data for an extra £2 per month - it includes tethering to other devices, too.
It's an upfront cost of £79 for the 16GB model, while the two tariffs work out at £34 and £36 a month, respectively.
The 32GB iPhone 5 will set you back £89 on Three, while the two tariffs work out at £37 and £39 a month, respectively.
You'll need to pay £109 for the 64GB handset - the two tariffs work out at £40 and £42 a month, respectively.

Hands on: iPhone 5 review
Vodafone's flagship tariff is the £47 Red Data plan, so you'll get a free handset, unlimited calls and texts, plus 2GB of internet.
Vodafone has confirmed this will cover you for FaceTime over 3G (but if you're planning to do anything like this, you're probably better off going to an unlimited tariff). It still seems rather expensive for an unlimited tariff compared to Three or T-Mobile, though.
The other tariffs also have unlimited texts and calls (aside from the cheap £33 plan, featuring only 600 minutes talk).
Monthly iPhone 5 contract costs are £47 (Red Data), £42 for 2GB of internet, £37 for 1GB and £33 for 500MB. Handset costs are free, £49, £99 and £149, respectively.
The monthly costs remain the same for 32GB - so that's £47 (Red Data), £42 for 2GB of internet, £37 for 1GB and £33 for 500MB. Once again, calls and texts are unlimited, apart from on the cheaper tariff, which gives 600 minutes of talk. Handset costs are where things change - at £89, £149, £209 and £269, respectively.
Monthly costs are the same again here - so that's £47 (Red Data), £42 for 2GB of internet, £37 for 1GB and £33 for 500MB. Once again, calls and texts are unlimited, apart from on the cheaper tariff, which gives 600 minutes of talk. Handset costs are £169, £229, £289 and £329, respectively.
