Will metal be in iphone 4s when updated to ios 8?

Ios is coming out and I'm really confused with metal like I understand what it does but will it be on iphone 4S when I update to ios 8 because the iPhone 4s have a A5 chip and it said it is compatible with A7 chip so with it be compatible with A5 chip?

You can install iOS 8 now if you register your device's UDID with a developer account through a site like http://www.udid.in/. It's $5, and then you can try the new OS before everyone else. That's how I got it on my 4s.

You can use iOS 8 on the iPhone 4S no problem, it may be a little slower than the 5S but it will be fine. You are welcome to try it by getting a UDID activation for iOS 8. You can always go back to iOS 7 if you don't like it. Just a heads up though you probably will not be able to use the iOS 9 beta on it, you should upgrade to the iPhone 6 when it comes out in the fall!

  • Updated iPhone iOS 6.0 and it deleted All MY CONTACTS I do not have anything stored on icloud. Now, I do have all my stuff stored to my computer on iTunes, i just tried to restore my iPhone, but my contacts are not there. I'm very frustrated and mad that this happened.
  • My itunes says it hasn't updated een though I updated it? I went to update my iphone and it said I had to update my itunes first and restart my computer (i have a macbook.) So I did all that and went to try and update my phone again and it still said I had to update my itunes first so I did it again and it is still not allowing me to update my iphone. It still says I need the latest version of itunes. What am I do wrong!
  • My iPhone 4s was jailbroken and I updated to the ios 6? I had no idea that my iPhone was jailbroken since I bought it from my dad's friend and now it's stuck in recovery mode and I tried iTunes to restore it but it won't work what do I do?
