Hey, I am really into the iPhone, and want to purchase one, but I need some clarification. I am an AT&T customer already, have been for a few years. I have family unlimited texting, so I want to know if that will carry over onto iPhone. Also, will it cost any money when activated (Such as activation fee or 2 year commitment?) besides the $20/month thing. And finally, I have seen lots of posts here and the Apple forums about iPhones breaking because of being dropped. I think I want a case.. So, what is the best case that isn't too bulky, but protects the iphone well? Thanks in advanced to everyone. Please feel free to let me know about anything and everything about iPhone I should know about. Thanks again
