Three from the UK just published a video giving their sneak peek of Nokia’s upcoming smartphone, the Nokia E7. They also mentioned it’ll be available on their network early 2011. That’s certainly different from Nokia’s promised release of December 2010, so some of you may be disappointed. Three pointed out the features that stand out on the E7 over its younger brother, Nokia N8, such as the bigger 4-inch Clearblack screen and the slide-out keyboard. Take a look.
