HTC's Sense UI (user interface) includes plenty of features that could make those with vanilla Android jealous, most of which involve the home screen. Phones running the custom UI have their own set of high quality widgets, which includes a "flip clock" that plenty of Android users seem to clamor over. The widget itself is four icons wide and two icons in height, and includes a clock that flips between numbers, the temperature, and icons to denote the current weather.
If you've been trying to get a Google Voice invite, you know how scarce these bad boys are. However, if you are a student with an .edu email address, you are in luck. Though it may not be the most well-timed release (exclusively for students near the end of the school year), this is still a huge plus for them.
To receive the service, all you have to do is sign up here with an e-mail address ending in ".edu", and wait for Google to send the free invitation "within 24 hours."
