Version:
Shows you the weather right on your springboard, and fits well with most themes.
WeatherKelly wants to be your little live weather updater right on your springboard. It may be only specific to me, but the widget couldn’t very well figure out where I was. It was giving me weather for some place on the other side of the world. There are no manual option to select what city it updates for, I assume it either uses the cities entered in the Weather app or uses the GPS. Either way it did not work at all.
Once again, this might only be an isolated issue, but don’t expect it to work 100%.

Does this run a deamon or is it a mobile substrate?
@TY
Actually, it uses WinterBoard, so MobileSubstrate
Do you have to SSH to get it to show the weather for your area?
@Justin
I’m not sure, but there were no instructions with the app.
The settings for the app are in:
/private/var/stash/Themes.abErZQ/Weather Kelly.theme/Private/configureme.js
Your path should be similar but the “Themes.xxxxx” may have a different string.
