We've seen this play out numerous times before: a celebrity Samsung spokesperson (typically), supposedly a Samsung smartphone user, messes up and accidentally tweets something from his or her iPhone.
What we haven't seen before is a company itself make the same type of hilarious faux pas. Well, now we have.
The official BlackBerry Twitter account this week sent out a tweet from an iPhone of all devices. The tweet has since been deleted but The Verge managed to capture a screenshot.
Again, this isn't the first time, and likely not the last, we've seen such a misstep.
For instance, there was a time when Soccer star David Beckham was a Samsung global brand ambassador. And during that same period, he was also an avid iPhone user.
And as another quick example, here's a shot of supermodel Kate Upton helping promote the launch of the Galaxy Note 10.1 tablet back in August of 2012, complete with her trusty iPhone by her side.
