Hello I see the iPhone 5 is not much different than the actual iPhone, just a few enhancements but... my question is: Can I buy the actual iPhone once discontinued? It is gonna be cheaper. The iPhone 5 will have a faster processor (so what) and may be thinner (I do not care). Besides that I haven't seen any other enhancement. I believe I would go for the 4s at a cheaper price. Any opinion? Thank you.
