Right now I have the IPhone 4 and did not update to the Iphone 4S. I might update to the Iphone 5 but I am going to wait until I hear some recommendations first. I know lines were for miles today. I still have 9 months left on my 2 year contract so maybe at the end of that I will upgrade. It is expensive to update 4 phones though (family of 6, only 4 have phones at this point though).
