Hi friend,
Please follow the below steps, hope it will resolve your issue and you will also be able to use whatsapp like others-
1- fully unstall the whatsapp from your mobile. Goto Settings > Apps > manage apps > select whatsapp to unstall fully.
2-download WhatsApp 2.11.238 again from 1Mobile Market and it would be around 14MB file and install it properly.
3-Goto your home page > here you will be able to see whatsapp icon > do not open it > Long press the whatsapp icon > two widget icon will be displayed on the below of the home page > click on the right side widget > it will open widget page > scroll down >
4-select whatsapp tile showing msgs (not the original whatsapp icon) > now it will move to home page with the whatsapp widget > do not open the original whatsapp icon > Now here is a trick, if u tap at the white msg area of the icon u will again get a "device not supported" msg but if u tap the green header of the tile contacting whatsapp icon....then you will be redirected to the whatsappp home and can see your mesages.
Thankx,
Chandan Singh
