For starters, it is said that 3rd party application performance has increased, allowing developers to build apps which will run fast and smooth just for you. Not only that, Gmail calendars on BlackBerry 10 will run fine and dandy from now on with the new update, in addition to improvements in the BlackBerry Hub which allows you to log calls as well as log how conversations are handled. The camera should also see an improvement especially in low light conditions, and the Web browser should also be able to handle video playback better, too. The BlackBerry 10 software update weighs in at approximately 150MB in size, so it would be best to stick to a Wi-Fi connection for a faster download.
