My friend given me his brothers old iphone which he uses as a ipod (he and i are both android users) and told me to do what he calls "the iphone challenge" basically what i have to do is use the iphone for a week and have it all set up as a daily driver. Currently im waiting for the ios 7 update to get done before i move a long to much, but what is there that i should know as an Android user. Like will my number be stuck as an imessage number once its on my line? And will i have any problems putting my Android back on my line? Stuff like that. Let me know every helpful tip i should know as someone that doesnt use ios a whole lot
