Hello everyone. I am going to be getting a new iPhone for my bday in December to replace my 4S. I actually am pretty happy with my 4S, but I am planning on getting the Apple Watch and so I am going to be getting the 5c or 5S. So, I could get a used iPhone 5c for around $300. But, I might be able to switch to T Mobile and get a 5s from T Mo for either $450 or $350, depending on how much I would get for my 4s trade in from T Mobile. So, should I get the 5S or the 5C?
