Should I get rid of my iPhone and get a basic phone?

I've had an iPhone for 2 years, and my contract runs out 9/2/12, should I get a 4s or a Pantech Jest 2?
I want to save my dad money, and all I really use my iPhone for is music and Facebook.
My friends say I should stick with my iPhone, but I don't know…
Share your input, thanks

Well all i can suggest getting a tablet phone, I myself used to carry a smartphone, And a tablet now i carry ONE.
