I recently bought a nokia lumia 820 on 8 may but soon i m facing some problems with it. My whats app is not working. even though i tried reinstalling it several times but d problem is dat it keeps on showing not connected in d settings option. N viber i cant even connect to it. same goes for we chat as well. I cant send any message to my friends on whats app n neither can dey. Even though dey can see dat i m in whats app. Another problem is with my datacable. My laptop does not recognise it. i m using a dell studio laptop with windows vista. But whenever i connect it through d datacable the installation process is not complete. they ask me a cd in order to continue to install it but i havent received any cd with my phone. I tried asking a nokia person frm where i bought it but it was of no help. So plz help me soon. i m frm guwahati, assam-781022
