This lock screen is awesome at first glance it just appears to be a full screen minimal weather lockscreen but if you slide the weather image to the right an array of details are revealed including a nicely styled forecast. Uses gps (my location app needed) or the normal yahoo weather code either works great. A few settings options found in the Config.js file.

The awesome theme I'm using in conjunction with this lock screen widget is inspire by Junesiphone check it out available for i4 and i5.
