Should I upgrade to the iphone 5s or wait?

I currently have the iphone 4s and know that I should be able to upgrade soon. Or I could wait for the iphone 6…

Added (1). Thanks for your opinions.

Just wait for iphone 6,

I can't see much innovation in Iphone 5s and 5c.

Iphone 5s is a higher-priced iphone 5 while iphone 5c is a plastic iphone 5… Lol

The iPhone 5s finger print sensor looks cool.plus its really really fast and has the slow motion camera which i find really useful.
wait for the 6 if your 4s is still performing well

  • Should I upgrade to the iPhone 4S or wait for the Samsung Galaxy S4? I have the option to upgrade from my old black berry curve to the iphone 4s for free, or I can wait a month to get the samsung galaxy s4. Also for free. Sorry I made a mistake, the Samsung Galaxy S4 I would have to pay for that one but it would be cheaper for me because I'm upgrading.

  • Should I upgrade to iPhone 6s or wait for the 7? Ok so I have an iPhone 5s 16gb right now and was wondering what your guys opinions were on if I should buy the iPhone 6s Plus 64gb or wait for the iPhone 7. My 5s has been really slow and freezing a lot, and I also can't keep a lot of stuff on it because of the low storage. IIm not sure if I would be able to deal with it for 7 months but I want your guys opinions.
  • Should I upgrade to iPhone 5 or wait for the next version? I'm eligible for an upgrade with Sprint. It seems like iPhone models generally don't last too long before a newer version is released. I don't want to upgrade and months later a newer version come out. Any thoughts on how much longer the 5 will be the newest version and your opinion on if I should upgrade now or wait would be very appreciated. (Btw excuse my name I make beats for rappers lol)
  • Should I upgrade to an iPhone 5s or wait for the iPhone 6? My phone is eligible for an AT&T Next upgrade and I was going to use it to upgrade to the iPhone 5s, but then I realized that the iPhone 6 will come out this year, but probably not until September or October. Should I upgrade now and then upgrade to the 6 at his time next year or wait it out and get a 6 then upgrade to a 7 after that?
