Updating to ios 7 via ITunes? Is it possible? What do i have to do?

I have an Iphone 4S and i want to update the software to IOS 7.Is it possible to do it via Itunes if I connect my Iphone into my laptop. What do I need to do?

Added (1). Also do you have to have Wi-Fi to download it?

No you have to go to settings>general>software update and it will all make sense

The best way to upgrade to iOS 7 is to get an Android phone, because that's all iOS 7 is, ideas stolen from Android.

You can either do it via iTunes or directly on the phone…

From what I've heard, updating via iTunes is a huge pain, just like everything on iTunes.
Just do it through the phone itself.

  • Will updating my iPhone apps affect my phone speed as how updating the Operating System (OS) will? Currently I'm using the iPhone 5s on iOS 8.3 I know if I were to update my phone to the latest OS I may notice some slowdown on my phone's performance, since it may not have the "muscle" to handle certain functions. Many apps now are optimised for iOS 9 and/or the 6th generation phones. Will my 5s' speed performance slow down if I update my apps? Will the app's performance slow down?
  • Will updating from ios 6.0.1 to ios 6.1.2 remove everything? I know that if you 'Majorly' update your iPhone it will erase everything from your iPhone like updating ios 4 to ios 6, but what if you are just updating your iPhone from ios 6.0.1 to ios 6.1.2 on the same version, is there any difference or it will also remove everything?
  • Updating iPhone 4 to iOS 6 software without itunes? My phone said it can update software but apparently without needing to connect it to iTunes. So its updating software now but through the phone by itself. Is this normal?
  • Updating iOS 6.1.3 to iOS 7 Beta? And i have an iPhone 4 running on Verizon, i'm trying to get the beta for iOS 7 because it looks really cool. I'm not computer ignorant, i just can't seem to find how to do this, my iPhone is not jailbroken or unlocked. I downloaded like 10 different files for ios 7 and they all give me an error saying they are not compatible
