Samsung Corby II GT S3850: How to download WhatsApp:

>>> From extended research, I've noticed a lot of blog posts about upgrading the operating system to Android firmware up to Jelly Bean and the use of "upgrade to firmware" = this is a false statement and the loose term of what that is. Meaning these bloggers are misusing that term. What these really are: it is a Firmware designed to look and feel like that Android version but it is not the exact version. It is only a "theme." So, in answer to your question. No, your phone can't run WhatsApp because it is not compatible with your phone's original operating system.

From the WhatsApp compatibility requirements the least Android version the app can run on is Android version 2.1
