還有，剛剛看到他們建議的步驟，節錄貼上來：
前提是要先升級至5.1.1喔~
How To Use Absinthe 2.0:
(如何使用苦艾酒2.0)
1. Make a backup of your device in iTunes by right clicking on your device name under the ‘Devices’ menu and click ‘Back Up’.
(重點就是先備份~)
2. Once your backup is complete return to your device and go to Settings – General – Reset – Erase all Content and Settings. This will make the jailbreak process much faster.
(備份好了後，請至設定>一般>重置>清除所有內容及設定，這樣會讓JB快一點)
3. Open Absinthe and be sure you are still connected via USB cable to your computer.
(打開工具且接上你的設備)
4. Click ‘Jailbreak’ and wait…. just be patient and do not disconnect your device.
(按下Jailbreak，再來就是等，途中請不要讓你的設備和電腦斷線)
5. Once jailbroken return to iTunes and restore your backup from earlier. Right click on your device name under the ‘Devices’ menu in the left panel of iTunes and click ‘Restore from Back Up…’ then select the latest backup you created before. (restoring this backup will return all the content previously on your device ie, apps, photos, etc.)
(JB完，就可以回復啦~)
6. Thanks for using Absinthe, enjoy your jailbroken iDevice!
(感謝各位使用苦艾酒和看我的文章(被打)，好好享受JB後的設備吧~)
Enjoy it :D~
