Q: ios 7.1.2

Install an app on an earlier version of iOS or OS X - Apple Support

I'm sure that's all true.

Therefore, you will not be able to use those apps on an iPhone 4.

You would need a newer iPhone, or use some other app.

Try this, maybe it will help:

is there somewhere else like this?

What do you mean? About all you can do is search for old version of apps but they are becoming scarce for iOS 7.

This is a user-to-user technical support forum for Apple products. I'm not sure why you'd be looking for anything to do with Yahoo here. Or, I just don't understand what you mean.
