I don't know if anyone was planning on signing up for the Orange data tariff, but you may wish to think twice going by this article:

About as useful as a chocolate teapot if that's accurate. I think VF give you 15Mb on their PAYG data tariff for £1/day which really puts the Orange plan to shame. Of course it's something like £2/Mb after that which is ludicrous.
