ake this with a pinch of salt, but according to the Twitter account of Samsung Nigeria, BBM will soon launch as an exclusive on Samsung's Android phones.No, we're not entirely convinced about that, not least because it doesn't make a lot of sense. After all, BlackBerry will want to push this as wide as it can and with an iOS app already being considered by Apple, limiting the Android distribution would be an unusual move.But that's the message from a specific Samsung Twitter feed, with the claim that Samsung has an exclusive and it will be available from this Friday. BlackBerry is also distancing itself from talk of exclusive deals too, which adds more doubt to what Samsung Nigeria is saying.But there may be no smoke without fire. Could BBM be arriving across the board on Friday? As we said, the BBM app is with Apple - and Friday would be the perfect time to launch an iOS 7-friendly app on that platform. If iOS is coming, why not Android too?We'll have to wait a couple of days to find out if there's anything in it. If there isn't, we'll think twice about believing regional Samsung feeds in future.
