Why won't my itunes allow me to update my iPhone?

My iTunes won't let me update the latest version of iOS on my iPhone because it says I have to update my iTunes on my computer. So I updated my iTunes and went to update my phone again and it still said I had to update my iTunes and I did it again but still no luck. What could I be doing wrong?

If your iPhone is too old, you can't download the iOS onto it.

  • Why won't the Apple store allow me to see my updates? I have an iPhone 3GS on iOS 6.1.2, and I'm having trouble with the app store. I can download new apps, and I can see the red number 4, letting me know that I have 4 new updates. However, the updates section stays blank and will not show me what apps need to be updated! What do I do! Is anyone else having this problem!

  • My iPhone 5 won't allow me to activate it? I'm in the US and connected to a wireless network- 100% sure tested. It is saying "There's no SIM card installed in the iPhone you are attempting to activate. Device is activated on CDMA US network. International roaming requires a SIM. What does this mean, why is this doing it, and how can I fix it? I'd like my iPhone to look exactly like my iPod does.
