After ios6. 1 jailbreak, the weather flashed back, but the weather flashback plug-in could not be installed. What happened?

This is a BUG in 6. 1 jailbreak. In order to solve this problem, the jailbreak god later produced the jailbreak tool of 1.5.3 version. If you are the first batch of jailbreak tools, there is no solution to this problem at present. You can only escape from prison when the next generation system is released. Now the latest 6. 1.3 system does not support jailbreaking.
