BlackBerry announces SDK for 10.3, tips a square-screened 4.5 inch device
Picture alleged to be that of the BlackBerry Q30
The new hardware will continue to use the 1:1 (for QWERTY equipped models) and 16:9 (for "All-Touch" phones) aspect ratios. Resolutions will remain 720 x 720 for the QWERTY models, and 720 x 1280 for the "All-Touch" phones.
But BlackBerry also hinted that there will be a new phone with a 1440 x 1440 resolution and a pixel density of 453ppi. These specs perfectly match up with the rumored BlackBerry Q30/Windermere, which is a squarish-shaped phone with a strange QWERTY keyboard that lacks numerical keys and keys for punctuations.
Rumored to be launching in November, is a device called the BlackBerry Classic, formerly called the BlackBerry Q20. This phone goes old school with a physical QWERTY keyboard, a track pad and function keys. Battery life is expected to be tremendous. The phone will be released with BlackBerry 10.3.1 pre-installed. A 10.3.1 SDK will be available later this year.
