>Someone to sort your phone or your mobile company out when you do not know what to do.
There are a surprising number of people out there who don't know their way around their mobile and will happily go into a shop and get an 'expert' to help them change contracts, move personal information between phones etc.
The trouble is that whilst there is a market for such services, I doubt it can sustain the overheads of the Carphone Warephone/PC World barns...
