'3' are doing 30 day contracts £15 for 5gb of downloads on a 30 day contract. I bought this last month and phoned up asking them if I could extend the usage if I pay extra. They told me they are allowed to give me an extra 10gb for free per month. So basically now I have the same deal as I would if I was on a 2 year contract. £15 for 15gb and no long contract.!!!
