Support for BBM 7 has finally come to those BlackBerry users who are running older operating systems (OS 4.5 and 5.0). When we told you about BBM 7 leaving beta back on December 10th, BBM 7 was only available for OS 6, 7 and 7.1. RIM promised that early in the new year that they would offer support for older OS phones and they've come through albeit very quietly.
BlackBerry Messenger 7 for you older OS users now offers BlackBerry Voice. This allows you to make phone calls to your BBM contacts over Wi-Fi. BBM 7 offers up more goodies as well, such as 16 new emoticons, split screen feature and direct BBM Update notifications.
