So, here is my work issued +BlackBerry 10 phone running BB10 built yesterday. I had the device last week but I couldn't get it to boot, but this week it's good. I finally got it hooked up to BES today so I now have work email from outside the office (RIM is a very email centric company). Still waiting on the SIM to activate, but Wifi works well for the time being. First impressions: it has some glitches as any trunk build has, but it's good enough to be a daily driver so far. I think we have a good product here.
