The class action lawsuit against AT&T's US iPhone exclusivity has been certified, which means a judge thinks it meets the legal requirements to go forward. If you remember back, The crux of suit states that customer contracts are 2 years, but the AT&T exclusivity is 5 years -- so customers were falsely lured to AT&T for 5 years, not 2 -- if they want to keep iPhones, that is. The lawsuit seeks to include all current AT&T iPhone customers.
