Will BlackBerry ban staff from iPhones during work hours? Company tweet sent from competitor device

BlackBerry may need to ban staff from using competitor devices after a tweet posted on the company account was sent from an iPhone.

That's according to Julie Towers, Board Director at Penna who adds that companies must develop, engage and inspire staff to ensure that their expectations of staff are met.

The tweet in question read: “Keep up with the conversation on @Twitter.” and while at first glance, there appeared to be nothing wrong with the message on closer inspection, small text at the bottom read: “via Twitter for iPhone”.
