Compare and contrast:
I just finished with a 1-month rolling sim-only contract with 3 (www.three.co.uk).
I'd bought the HTC 7 Mozart for £350ish off Amazon, signed up with 3.
100 minutes, 3000 texts, 1GB data. £10/mo. Can tether, etc.
You guys really do get done up the arse with no lube, don't you?
