What iPhone should I upgrade to?

I have an iPhone 4S in black, which I've had since Feb 2012 (it's September 2013 now) and my contract finishes in January 2014. I don't know wheather I should upgrade to an iPhone 5, iPhone 5S or iPhone 5C what would you recommend?

Get the iPhone 5S or if you don't want to spend that much get the iPhone 5C

January is 4 months, decide then.

No idea

I would say, go for 5S. Better get the most high end/updated one.

I recommend all of them because all of them are great. Really, it depends on your style. As you may already know, the iPhone 5s has a fingerprint identity sensor, which personally I think is amazing; so, if you have enough money, I think that the iPhone 5s is worth it.

The 5c is basically the 5 in new packaging so I would either go with the 5 which is about the same price as the 5c on most networks or really go for it and go up to the 5s if that is within your budget, it might come down a bit in price by then too.

Wait till 2014 if you buy now you will be screwed when they start using sapphire crystal and graphine parts and displays
