My mate said something like iTunes on the computer but I only have a laptop? Technology ay! Please help and give me the steps for what I have to do to download it etc thanks x

You can't get it

Yes, you can get iOS 7 on the Apple iPhone 4 although it does not include all the features that it would particularly have on an iPhone 5, 5c or 5S. To check for the iOS 7 update on your iPhone, go to settings, general and software update and you should be able to click download. It should then start downloading and restart your iPhone. To update it through the computer, plug your iPhone into your computer/laptop using the lighting to apple USB cable that came with your iPhone and open iTunes (If you don't have iTunes already installed, please install it before preceding.) In iTunes, in the top right corner, find the tab that says iPhone and click on it. After clicking on it find the button that says "Check for Update" or "Update" and click on it. IOS 7 should immediately start downloading and download and restart your device.

You could update using iTunes on your laptop.

Just download & install iTunes, connect the iPhone & it would tell you about the update.

Yes you can get it I don't know about 4 but I think it will show up on your settings that you need a new update
