Yesterday 14th June 2012 Research in Motion held their UK Blackberry 10 Jam event in Vinapolis near London Bridge. The day was full of information about how to build native or HTML5 applications on the new Blackberry 10 operating system. RIM also gave away an Alpha dev 10 phone, which looks pretty similar to an iPhone, but without any buttons (apart form the power button). The unit also has a micro USB connector, an HDMI connector and a tray and slot for a micro SIM. After setting up the device (using your Blackberry ID), you get to the home screen, which gives you 2 apps, the camera and a browser (and of course settings which is part of the OS). Anything else you have to write yourself. In the US, the devices were given out with SIM cards and they are meant to be fully operational as phones (and allegedly there's even a dialler within RIM somewhere). It is possible to pair the device with a Bluetooth headset and then receive calls by answering through the headset. Also in the US developers were promised free upgrades to official Blackberry 10 devices when they are released. This may be the dying spasms of an organisation trying to attract developers with gifts, but Blackberry's OS 10 is actually rather good.
