Just bought a passport (AT&T) version. Had the gsm version for about a month and really enjoyed it, probably my favorite phone I've ever used. My iPhone 6+, even with jailbreak, just doesn't cut it when most of my phone use is for communication.
I think if BB can make somewhat of a comeback but they need a cheap, and i mean dirt cheap, phone that can compete in developing countries. They also need to get more apps on board like snapchat or netflix or something. If they maintain only like 1-5% market share thats still enough to survive
