Penny Boards.and IPhones and Christmas?

So, i've been given the option, to get an iPhone 5 with no other presents, or an iPhone 4s with presents. I think i have come to the conclusion that i will get an iPhone 4s because i really want a penny board. This brings me to my main question. I'm 15, have size 7 feet, a girl. I only said that because of the size difference in the boards. I'm not sure whether i should get an original penny or a nickel- which is slightly larger. I've been thinking nickel, then i have suddenly changed my mind to a penny. Just so you know, i can skate, kinda snowboard, roller skate, ice skate etc. Please answer!

I have the iphone 5 it is no different from the 4s i also have a penny board size 9 foot if you are worried about the size of the board then don't it may take some getting used to i would suggest getting the penny and the iphone 4s
