The Giffgaff offerings look good now they have been changed but is it worth it when people all report slow speeds on the data. ?
Who are 'all the people'?
I can't say I seem to suffer form generally slow speeds, I've never really bothered to go round testing it, but it doesn't feel any different really yo my wife's iPhone on O2. Certainly seems fast enough when on a good HSPA+ connection.
As ever though, it's the people who are unhappy with something that will make the effort to post about it online.
