For those interested in BBM for iOS, it appears development is one step closer to launch as cross-platform BBM beta testers have recently received emails to register and test out the latest version, according to BlackBerryOS.

The program is not available for everyone, but if you have received an email like the one shown above, you’ll find it available under Eligible Programs. Much like it will be when it goes official, the beta version of BBM for Android requires v4.0 (Ice Cream Sandwich); while the beta BBM for iPhone requires iOS 6 as a minimum requirement.

BlackBerry has said BBM for iOS is set to launch “before the end of the summer” at its most recent earnings call, where the company announced a net loss of $84 million and the PlayBook would not get a BlackBerry 10 OS upgrade.
