When it rains it pours for BlackBerry. Although there has been considerable interest in the new cross-platform version of BlackBerry Messenger, BlackBerry announced on Monday that the launch of BBM for iOS and Android has been delayed for at least another week. BlackBerry’s BBM chief Andrew Bocking said in a company blog post that the delay happened after “an unreleased, older version of the BBM for Android app was posted on numerous file sharing sites,” which “resulted in volumes of data traffic orders of magnitude higher than normal for each active user and impacted the system in abnormal ways.” The BBM team is now working to completely block the leaked versions of BBM from accessing BlackBerry’s servers before it launches the final version of the app. Bocking said that the fix isn’t expected to occur this week.
