BlackBerry re-launched the Android and iOS apps yesterday, after problems with a rogue version of the Android app forced BlackBerry to suspend the rollout for almost a month.
Despite this initial huccup, however, BlackBerry claims that yesterday was one of the best single-day openings for a mobile app ever.
BBM quickly rose through the rankings on the App Store to become the number one free app in more than 75 countries in the first 24 hours, including the US, Canada, the UK, Indonesia and most of the Middle East, according to BlackBerry.
