注意事項：
To jailbreak your iPhone 4S (running iOS 5.0 or either 4S version of 5.0.1**) and/or your iPad 2 (all Wi-Fi only, GSM & CDMA devices supported; must be running iOS 5.0.1**)
iPhone4s：要在iOS5.0或5.0.1
iPad2（WiFi/GSM/CDMA）：要在iOS5.0.1
**NOTE: If you haven't yet heeded the advice I gave weeks ago – before you take one step further, upgrade your firmware to iOS 5.0.1 NOW! (Unless you need an iPhone4s Unlock) Also, we don't mean to beat you over the head with this warning, but please remember: you should not update to iOS 5.0.2 when it's released, or you will lose your jailbreak! Bookmark our GreenPois0n blog now, and be the first to know the next time we advise our jailbreak users to safely update their iOS firmware.
基本上如果你還不是在iOS5.0.1，請先升級（除非你需要解網路鎖），再來就是老生常談，5.0.2（或是下一版的官方更新）出來的時候請不要升級。
