Ready for a switch

Hello all. I'm new here, and have a question. I've had several iPhones since they have came out. I currently have the iPhone 4. I've been looking to either a iPhone 5 or a Samsung galaxy rugby pro. I runs the ice cream sandwich. I'm new to the android world and don't know much about them. Does anybody own or know of any reviews on the ruby pro? The reason I'm looking at this certain one is because my brother has the flip rugby with the push to talk and likes it. So if I can get the ruby pro I can use the push to talk with him. I still want to stay with the smart phones. So if anyone can help me out I'd be greatful. Thanks
