The new Apple iPhone SE is now available. 

The new handset refreshes the design of the iPhone 5S, sticking to a smaller 4-inch form factor, but is packed with powerful internals to match the iPhone 6S. It's small, but powerful, and importantly, it's the cheapest iPhone in the family. 

It comes in 16 and 64GB versions and in a choice of silver, gold, space grey or rose gold. Pre-orders have opened, so it's available to buy from a number of retailers. Not all have opened up their deals yet, but we will update as more details are announced.

Unlike other smartphones, there are no free gifts handed out with the iPhone, so it's all about the cash and what you get for your money. 

You can buy the iPhone SE direct from Apple SIM free, leaving you free to choose your own talk plan direct with the network of your choice. 

The 16GB iPhone SE will cost you £359. The 64GB iPhone SE will cost you £439.

The cheapest month plan on EE is £27.48, but you're asked for £49.99 upfront for a 16GB iPhone SE, and you only get 500MB of data. The total cost of this option is £709.51. 

However, it's better to opt for the £29.99 a month tariff on a 16GB iPhone SE, getting you 1GB of data. It will cost you £719.76 over 24-months, so only £10 more than EE's cheapest option, for double the data. 

If you're after the larger capacity iPhone SE, you can get the 6GB model with no upfront payment, for £39.99, with 2GB data, however, you're paying £959.76 over 2 years for this.

Carphone Warehouse has lots of deals in lots of combinations. If you're after a really cheap iPhone SE deal, then for nothing upfront and £26 a month you can get a 500MB plan with a 16GB handset on Vodafone. 

That's a little limited, however, so you'd probably prefer to pay £59.99 upfront for the 16GB iPhone SE and keep monthly payments to £26. Over the course of 2 years you'll pay £683.99, but with 3GB of data on Vodafone, which looks like a hot deal. 

For the 64GB model, take a look at paying £69 upfront and taking a reasonable £31 a month plan on Vodafone. This bags you 7GB of data, for £813 over 24 months. 

For not much more you can get the 64GB iPhone SE with nothing upfront, on a £36 a month deal for 11GB of data. It costs £864 over 2 years.

If that's not enough data, stepping up to £34 a month will net you 2GB of data, and £37 a month will get you 4GB.
