I bought an iphone 4 from a friend who used it on a vodafone contract. I now have the phone but i am on o2. When I enter o2 sim card it wont let me activate phone. If i enter the old vodafone sim, the phone activates fine but no service ( obv as contract has expired )
If I then enter my o2 sim it just says no service and it wont let me see any contacts etc from sim card. How can I unlock this phone so that it accepts my o2 sim card ??
Any help please ???
