Hello all, I am looking for some extra opinion on what to do about my iPhone 4S. It needs two repairs. The battery needs to be replaced, and the screen has yellow spots on it, so it also needs to be replaced. Should I pay an approximate total of $160, or wait till my birthday in December and get a used/refurb iPhone 5/5c. I am sure the prices on these models will go down when the 6 comes out so I am sure I can score one for around $300 or less. What do you guys think? Should I just wait and get the 5 for my bday?
