I have 3 iPhones locked to Australian networks.
My iPhone 5 is locked to Vodafone (baseband 1.00.16)
My brother's iPhone 4S is locked to Telstra (baseband 3.0.04)
My girlfriend's iPhone 4 is locked to Optus baseband (baseband 4.12.02)
Gevey isn't working anymore, and I wanna unlock them to use it outside Australia, I heard about the IMIE factory unlock, how can I do this?
