Today BlackBerry unveiled an update to its SDK and debuted the QWERTY-sporting Dev Alpha C handset at its Jam event in Amsterdam to help coders build apps for BB devices with physical keyboards. It also announced the WebWorks SDK, which will support apps for the recently launched Blackberry Q10 handset. The software kit will let physical keyboards work "just as if (input) came from the virtual keyboard on a BlackBerry Z10" touchscreen device, according to the blog, letting devs create applications for both with "very little effort." The new handset will join BlackBerry's Dev Alpha B model for touchscreen smartphones and the freshly announced red Special Edition Z10. Want more info? See the sources below.
