How to install an older version of the application?

Question

iOS

Hello.
I have iphone 4
ios 6.1.3
No Jail
Let's say iphone has app version 2 installed
So itunes has app version 2 file
But I want to install app version 1
again itunes application version 2, drop the application file 1 into the itunes folder and thus install the application version 1 on the iphone?
2) How can you install an older version of the application, given that you already bought it?

Answer 1

1) Can I download the version 1 application file from the Internet, delete the version 2 application from iphone and itunes, drop the application 1 file into the itunes folder and thus install the version 1 application on the iphone?

No. Each application (ipa) is signed for installation on a device, with a specific Apple ID. You had to save your ipa file from the iTunes folder, then it would be possible to install it again.
