So what operating system are you using and what carrier are you using? and WHY do you use them ? Me: Android - At&t Why: Ive tried IOS and its just too , childish for me. I love android because im used to linux, and you are more "open" in android. ive been with att since 2008. ive had less than 5 dropped calls, and so far have never been in an area without service, where as my friends have been with me through sprint and have no service. ATT customer support has been A-1 so far. and always worked with me.
