It has been reported that due to technical issues, WhatsApp Messenger has been removed from the Store. WhatsApp tech team is now working closely with Microsoft to resolve the issues & hope to return to the Store shortly. Yes indeed I tried to search for WhatsApp Messenger & is no longer in the Store. As I understand this is due to Window 8.1 update that WhatsApp is having issues with. Thing is if I were to purchase a 930 which comes preloaded with 8.1 then I would not be able to use WhatsApp in my phone. I wonder those who are using 630 can use WhatsApp on their phone. I'm sure they will resolve this issue sooner or later but for now is a deal breaker. Cheers mate!
