Can I download/install iOS 8.0 to my iPhone 4?

Yes

No you can't install iOS 8 on an iPhone 4. The latest iOS version for an iPhone 4 is iOS 7.1.2. Only iPhone 4S and upwards support it.

Nope. IOS 7.1.2 is the last.

  • Why can't iTunes download and install iOS 7? I can't update to iOS 7 with just my iPhone. I need Wi-Fi. So I've tired downloading and installing 5 times already in iTunes. Each time it tells me it's gonna take 25-26 hours. But when it gets to 21 hours left, a small page would appear saying "An unknown error has occurred (9006)." It's getting me frustrated. Is there something I'm doing wrong while updating to iOS 7?
  • Why can't I download and install iPhone update? I have an iphone 4s, currently version 5.1.1 (never bothered to update), and I want to update it to ios 6.1.1 (I have a notification on my iPhone settings). It says that I must have at least 2.8GB of data available, I've checked and I have this exact amount of data free… However, the button on the software update page saying 'download and install' is greyed out and I can't click on it. Can someone help, please?
