How to upgrade iPhone 4S to iOS 7 instead of iOS 8 or 9?

I currently have iOS 6 on my phone.
From iTunes, I can go directly to iOS 9.
From Settings > General > Software Update, I can go to iOS 8.

I don't want these 2 iOS versions but iOS 7 instead. How can I upgrade to iOS 7 only?

Added (1). But I can still upgrade to iOS 8 right?

How to recover photos from Iphone 5?

Can you still recover these photos through some online program if you don't have a backup on your Iphone?

How to fix an iPhone home button?

If your iPhone is completely broken and missing the plastic cover and you do not have time to go to a apple store, if you aren't already at the home screen find an object that is real metal and push it onto the place where your home button should be. Then go into settings, go in general, go onto accessibility and tap assistive touch and turn it on. There are ways that you can change what you see. As for resetting your iPhone use the same metal object as you used before and hold that down onto the home button insert and hold that and the power button at the same time fro 10-20 seconds. Note: It may take time to find the right metal object.

Can I use an old Verizon iPhone 5C with MetroPCS?

I have an old iPhone 5C that is from Verizon. The contract is up and it is no longer on our plan. I want to give the phone to my friend and she uses MetroPCS.
I have been having a hard time figuring out how this will work and I need it explained in terms that I can understand (a lot of the stuff I have read has been too complicated for me to understand). From what I have read it shows that I can purchase a MetroPCS sim card and put it in the iPhone. Will this make it work with Metro? I want to give it to her for her to start a new plan with them with the phone. The iPhone was not unlocked when I bought it. Will this be possible? Basically I need these answers:
1. Can an old Verizon phone be used with MetroPCS?
2. Does the iPhone have to have been unlocked?
Thanks.
