Well, it happens to the best of us - the official BlackBerry
twitter has mistaken a fan account for Hyoyeon
Hyoyeon posted a photo of all her BlackBerry devices on her Instagram with the caption, "#BlackBerry They're cool". BlackBerry apparently wanted to show appreciation for her loyalty and tweeted, "Thank you Kim Hyoyeon @hyoraengi89 for this amazing shot! http://blck.by/29DwKuk #TeamBlackBerry show us more."
However, while the link itself leads back to Hyoyeon's Instagram, the account mentioned is not Hyoyeon's account, but a fan account that hasn't been used since 2015. Hyoyeon doesn't currently have a Twitter account.
Fans were quick to tell BlackBerry that the account was not Hyoyeon's, but it looks like they haven't corrected their mistake yet. Hopefully they do it soon!
