b2釋出時是說已經用b1的人只要再跑b2一次不要勾install cydia就可以了
但事實上若照dev team的做 會造成mobile substrate損壞
無法使用cydia上的程式(需要用到mobile substrate的)需要移除重新安裝mobile substrate
所以才釋出b3 修改了上述問題 b1的就真的只要再跑一遍b3不要勾install cydia即可
原文如下
Update #2: The b2 version of redsn0w includes the launchctl-related fix by @planetbeing as mentioned by @saurik here and here. As usual, you can just re-run redsn0w in jailbreak mode over your existing 5.0.1 jailbreak (even a PwnageTool one), making sure to de-select “Install Cydia” if you do. Always be sure to do a controlled “slide to power off” shutdown of your device before running redsn0w.
Update #3: The b3 version of redsn0w fixes a problem where re-running redsn0w over an existing jailbreak would cause MobileSubstrate-based apps to stop running until MS was installed again. Now you can re-run the redsn0w jailbreak step without worrying about that (but still remember to de-select the “Install Cydia” option if it’s already installed).
