Prison break, weather.

Go to cydia, open cydia, there is a search below, click it, then enter "weather" and search. The second "weather flashback repair" is it. As for the source code, you don't need to add the software source code if you can find it, but you can add it if you can't find it.

Cydia, management, software source code, edit in the upper right corner, add on the left, write down the source address, click Add, and a dialog box will appear to continue.

Search when you're done. In fact, after I escaped from ios6. 1.2 perfectly, the weather flashed back. How did I solve it?
