What immediately attracted me about this phone is its looks. Coming from the Android universe, I was nervous about its use as there is no touch "Back", strictly speaking, but in the end there is aps need. The entire interface is thinking "Functional". navigating the menus are in a very fluid and intuitive. It is true that it takes a little time to get used to the BlackBerry OS, but after one day with him, all functions are completely mastered. And then if we look how to do such a thing, the site is the blackberry;) Finally the phone is quite thin, and keeps rather well in hand. For comfort and to protect it, I also recommend the Blackberry pouch that goes with it. Blackberry thank you for this marvel of technology !!
