O2 that recently claimed of its iPhone 4 availability has thrown in the pricing details online.

One can have hands on over the device, at a starting price of £25 per month on a two year contract, and £30 per month on 18 months. But it comes strange as the 16GB handset costs £279 on the two year deal, and £209 on an 18 month deal.

On the other hand the 32GB iPhone 4, comes at a £323 on a two year deal, and only a bit less at £299 on the 18 month option.

For the interested ones, the deal comes with a free iPhone 4 16GB. Consumers will need to step up to the £60 per month tariff on two years, £65 on 18 months. On this plan, the 32GB variant will cost £29.

If the rumours go correct the Vodafone's figures will be £30 cheaper than O2 for a 32GB handset on a two year £35 per month tariff.

As in case of O2 an upgrade option for customers comes up where you can buy your way out of your current iPhone contract for £20 per month remaining, and upgrade straight onto a shiny new iPhone 4.
