I got an iPhone 4 from someone constantly buying new phones too! Then someone else gave me their 4s shortly afterwards. Free phones are the best phones. Any time I purchased a phone it was always something that could come in a rugby style or something similarly indestructible though. I do not like replacing them.
that new phone with the notification edge looked pretty slick. Still was too big for my liking though. You know, cause I want the phone to fit in my hand.
