This is an animated weather lockscreen with multiple options for weather configuration and non animated weather. This lockscreen uses GPS or Native Weather to get your location, no manual entering of a woeid is needed. GPS is set as default on install.

You need to have My Location app from Cydia. Install GPS Weather Lockscreen by crazyvivek to get the app. *Note~MyLocation app does not work on iOS 5.1 at present.

If you are going to use it as Native Weather, open Setup/Config.js and change var gps = true to false. To use as Native Weather you need Live Weather Icon from Cydia. Install and turn it on in Settings app. Then you can open the Weather app (stock) and ensure Local Weather is enabled which will set the city for you on the lockscreen.

Also in the Config file you can turn off animated weather and use static weather images in the background. Use of Native Weather has less text info on screen than GPS. GPS is pictured in the screenshots.

The moon animation at night is the bat signal. It will show on all conditions other thn cloudy/mostly cloudy.

Thanks to Subywrex for the Native Weather script and animated weather images. Thanks to Dacalme for the rewrite of the script to enable multiple options and languages. (French, Spanish, German, Italian) Default is English.
Special thanks to Metaserph for the Batman Layer work
