Additionally, I have two iPhone 4S's on the unlimited Sprint plan for $150 a month total (the company my wife works for has a 15% corporate discount). I researched the different plans and $150 a month for unlimited "everything" for two phones was by far the best deal I could find.
Very happy thus far!
When my current phone dies I'll probably do what you did and buy an Android phone. I understand they are great. Also, I guess I'm just not a fan boy.
