OK, here's my dumb question regarding building credit:
In the US, if you want a contract cellphone but don't have any credit, you can put down a deposit ($100-200) that you receive back after 6 months of "good" bill paying behavior. Anyone know of a UK mobile company that has a similar policy? I've poked around the websites and not found anything, and I'm a little too shy to go into a shop and ask outright.
