Forecast Cydia Tweak details
Forecast replaces your regular lockscreen clock with an updated iOS5 native weather widget. The updated widget includes the time and date and an icon to let you manually refresh the weather at any time. Forecast is smart enough to reduce data usage by only refreshing on the lockscreen at most every 15 minutes. Additionally, when weather updates are not available, you can still see the last weather and forecast with an unobtrusive icon in the corner to tell you that weather is offline.
