I really want to get an android of some sort, been leaning towards the galaxy s II or the galaxy nexus, however i want to keep my iPhone 4S as my main phone and be able to change the sim between the phones at my leisure. I have learnt however that this is not possible on the O2 network as the iPhone requires a seperate APN settings or something. Why dont O2 just make a universal data bolt on that you can use on any phone? is there any way this is possible? maybe a different network?
