How to downgrade iPhone application using iTunes

If you regularly backup you iPhone/iPad to iTunes there is a solution for app downgrade. You should do the app downgrade as soon as possible, while old version is still available on you computer.
Here are steps how to do application downgrade:
1. Delete application from you iPhone (be aware that all data in application will be lost)
2. Connect iPhone to a computer and open Itunes
3. Find the application that you want to downgrade
3a. If you have already synced applications, and new verision of application is in Itunes try to find old version in Trash, copy it to some folder and than drag it to iTunes. Now you will see old app version in iTunes. You can select to install it.
