Amidst all the news coming out this week about BlackBerry World 2012, RIM CEO Thorsten Heins said today that devices running BlackBerry 7 will not be upgradable to the newest operating system, BlackBerry 10.

According to The Verge, BB7 will still be available. However, it looks like it'll be reserved for more of RIM's entry-level handsets. Meanwhile, BB10 will be featured in its high-end devices.
