What iPhone better? What INE should i get?

I Head IPhone 5 having some problems so what Iphone better Iphone 5 or 4s

I own an iPhone 5 & I've heard no problems nor encountered any using the phone. So the 5 is obviously the one to get.

My little sister has the 4S and I have the five. Honestly, hers has so many more problems than mine. My 5 hasn't had any significant problems except sometimes it skips musics for no reason but that happens to all iPods sometimes on a bad day. I recommend the 5 if you have the money for it. If it is too pricey for you, go with the 4S or 4 because they are basically both the same thing anyways, except 4 has A4 chip and 4S has A5 chip, making it run faster than the 4. 5 has the A6 chip and supports LTE. The 5's screen is made of Gorilla Glass 2 (STRONG GLASS) and the screen isn't as elevated as the 4 or 4S so it won't break easily when you drop it. The back of the 5 looks much sleeker with the new aluminum and glass backing. That ensures that the back will not crack… That is the problem that some people were having with the 4 and 4S. So that's all the info I have for you but an iPhone really is just an iPhone. It is your choice whatever you get. I would personally wait for the 5S to come out or whatever Apple has planned next.
