Re: Post your lock screens or homescreens
Yes; there's an app named MyLocation in Cydia that you can download & install. This will (should) allow your weather display & forecast to change based on your location. If you use MyLocation there's an option called SigChange which you should turn ON. You can also modify the config.js file as AD1CTV mentioned, and input your location code. Should be something like "var locale = XXXXXX". Some weather widgets use the location code from Yahoo! weather, others use Weather.com. The config file (or maybe a ReadMe) should ID which one you need.
