Nearly a month after problems delayed release of its BlackBerry Messenger apps for iPhone and Android, BlackBerry said it had relaunched the app on Monday.Immediately after the relaunch, which occurred about 2:30 p.m. ET, some BBM customers, including CIO.com blogger Al Sacco tweeted that BBM wasn't working. BlackBerry couldn't say immediately how serious the problem was.According to a BlackBerry blog posted earlier Monday, BBM would be made available in Google Play, Apple's App Store and some Samsung App Stores for free.There's just one catch: People who didn't pre-register to get BBM must install the app, enter an email address and then wait for the rollout.
