BlackBerry has finally provided us with launch dates for its new BBM apps for Android and iOS. Just as we expected, the popular messaging service will reach Google Play first on Saturday, September 21 — before popping up in the App Store just a day later on Sunday, September 22.

Google has released an official AdSense app for Android and iOS, allowing AdSense users to keep track of their earnings on the go. You can keep an eye on your latest earnings for the day, see what you earned yesterday, and view your earnings for the month so far — plus lots more.

UPDATE: There are some screenshots of BBM for Android at the bottom of this post.

By now you’re probably already aware that BlackBerry Messenger is coming to Android and iOS this summer, but BlackBerry has been pretty quiet about its release since it was announced. We don’t know exactly when the app will arrive — though we do know it’ll be by the end of September.

But the Canadian company has now begun making the BBM beta for other platforms available via the BlackBerry Beta Zone.

We had expected BlackBerry Messenger to make its debut on Android and iOS on June 27 thanks to T-Mobile U.K., but when it became apparent that the carrier’s announcement was incorrect, we started to wonder just how long BlackBerry would keep us waiting.

But during a quarterly earnings call this morning, CEO Thorsten Heins again reiterated the company’s plan to make BBM a cross-platform service “before the end of the summer.”

Apple has begun charting iOS adoption figures to help developers establish the percentage of users running different versions of iOS. Google has been doing the same thing for Android developers for some time, and Apple’s chart only highlights the massive difference in fragmentation between the two platforms.
