Mobile data data

Yesterday's bill from my mobile service provider came in at 50.42 GBP for the month. Of that, I spent 20.95 GBP on data services, WAP browsing and downloads etc but not including texts- because of a "texts included" package I only spend a couple of quid on them. On that basis I'm in the supertax league i.e 40% plus for data services, and way above typical data ARPUs for UK mobile MNOs. Looked at another way, there's good scope for mobile data revenues. If I'm spending 20 quid, somebody else is only spending 2 pounds.
