HTC Sense Modification to my theme "Lighthouse 3.1".
This really isn't so much a functionality mod as it is a visually pleasing mod to Android, but it includes the sexiness Sense has always come to be known to have.
The Weather/Clock widget has been updated to include no extra features but now matches the matte style of 2.3, 3.0, and 3.1. Tapping the widget leads you to the 15 day forecast brought to you by AccuWeather. No that was not an ad, I just like their 15 day forecasts.
