Hello,
I would like to install a messenger into my device but unfortunately the operating system is quite old and Microsoft Windows is no longer supports Windows Mobile OS 6.0. I have learnt I can install Android 2.3.3 to my phone. I am not sure if I can do it. Firstly I have seen an article on here: https://www.howtochatonline.net/chat-apps/whatsapp/how-to-use-whatsapp-on-unsupported-version-of-windows-mobile-os/

I have some questions about that:
1-) I would like to get opinions of phone experts. All these steps are correct on those videos and text steps? I don't want to do something wrong.
2-) If I ever do these steps, does my phone get hurt?. I shouldn't try install Android to my phone at all?
3-) Anyone know what are exact minimum requirements for Android 2.3.3.
4-) If I can manage to install the Android 2.3.3 OS but if installation breaks some features of my phone, can I get back to Windows Mobile OS 6.0 and how?

I appreciate any help and thanks for those whoever answer my questions.

Edit: Btw There is any messenger application for my current os (Windows Mobile OS 6.0)?
