As outlined in the leaked 2012 BlackBerry roadmap, the two new Curves (9220, 9320) will feature a dedicated BBM key. These phones are ‘built to chat’. Of course, you won’t be able to take advantage of this great feature unless you’re in one of the emerging markets that they’re released in, or feel like having a friend ship one to you. Do you think a dedicated BBM key will be very useful? This features seems reminiscent to the HTC Facebook phone.
