Is it worth paying $220 to get iPhone 4s on a two years contract?

I'm planning to renew my cell contract for another 2 years and these are my options. Which one do you think is BEST?

iPhone 4s $220
Sony Xperia M2 $0
HTC Desire 510 $0
Nokia Lumia 635 $0

Why do you keep asking the same question?

I honestly would not pay very much for an iPhone at all. Unless you understand that phones break after a few months and you just have to buy more because thats how phones are. I think of it as I'll pay a couple hundrate dollers for something that won't break.

I have seen the design of modern apple devices and I've spoke with apple technicians, there just out for money, I wouldn't get it.

  • Would you buy a new iPhone every 2 years or 4 years? Why? If your not a fan of iPhones don't answer please. And would you buy the S models if you don't already own an iPhone?
  • Is the iphone 5 worth getting for a 2 year contract, and paying 200 dollars? I have a old blackberry but it works so I don't know if I should change it. I'm getting a verizon iphone
  • Is a used iphone 5s worth 220$? I bought a used 5s on amazon for 220dollars it is a B in the grading scale of how used it is. I currently use an LG leon and i've always wanted and iphone. I want to know if the iphone 5s is worth getting right now at that price
  • Is a two year contract actually two years? I just recently got a new job that will allow me to splurge a little bit and finally upgrade my phone. I hope to switch from Straight talk over to AT&T so i don't have to continue paying $300+ when I need a new phone. The iphone 6 is about $100 with AT&T s two year contract, and then I'm eligible for an upgrade. Will I be held in that two year contract or would I be able to upgrade earlier to a more recent version? How much does it generally cost to upgrade early?
