Same contract as the one that you can get from Tmobile, but this one has a cheaper initial payment for the phone. A lot of people have managed to haggle the price down, but here you don't have to and there is the possibility of £30 via topcashback.
T-Mobile £15 [info]
300 cross-network mins + 300 texts + Unlimited Text Booster 24 months
The phone isn't instock though, not sure why as its a new phone, but thought this might be useful info for someone.
You can add the phone to your basket however, i wonder if it would go all the way.
