O2 and Vodafone have followed Orange in announcing their iPhone 4 tariffs.

O2 have undercut Orange by offering the iPhone 4 16GB free on a contract which costs just £60 per month. Orange is only offering the mobile free on a £75 a month contract, which is a large difference.

Apart from this one difference both offerings are very similar. The only other difference is that O2 has made the iPhone 4 32GB £10 cheaper on each tariff option.

O2 also confirmed they will be stocking the mobile on Pay As You Go but unlike Orange they won’t offer it on the iPhone 4 launch date.

The Vodafone tariffs are pretty much the same as O2. The prices all match up with the mobile available free on a £60 a month deal. The only difference is instead of unlimited UK minutes you only get 3000 minutes per month.
