Tesco's iPhone tariffs

First off, there is a difference in the internet allowances. Orange allow 750mb a month and o2's is unknown, but is rumoured at around 8GB a month. Tesco, however, allow 1TB. But that is the start of the tariffs, with long intricacies involved.

Let's start with the cheapest tariffs. This is for an iPhone 3G 8GB, which is a hell of a lot cheaper than the 3GS. It is just over £700 on Tesco for 2 years with a £222 up front cost at the start. However, it is a £20 monthly contract which you can leave after 12 months, unlike o2 and orange which require 24 months of your credit card.

For every contract, Tesco is cheaper than its rivals. But we still need to see whether Vodafone will undercut them, but I don't think so. Tesco does have a difference, it requires you to pay up front as well as the contract, which helps in the long run.
