Good afternoon wonderful nairalanders, am here to share my own personal view for those using blackberry or any android phone that don't support whatsapp anylonger. It's kinda easy what to do to make whatsapp work on your phone again just follow these easy step.
1. Go to your phone settings
2. Click on date and time
3. If your date is reading 16-1-2018
4. Just back date it to any date of ur choice, like 16-10-2017
Note: it's tested in blackberry and it works perfectly. So Goodluck to those who don't have much to purchase a new phone that support whatsapp
