如果你的iPad已經JB 4.3.1完成，可以用以下方式簡單開手勢多工
1. 在Cydia安裝iFile
2. 執行iFile尋找/Applications/Preferences.app/General.plist
3. 點選檔案選直接編輯文字
4. 尋找以下段落
原始：
<dict>
<key>cell</key>
<string>PSGroupCell</string>
<key>footerCellClass</key>
<string>MultitaskingGestureExplanationView</string>
<key>id</key>
<string>Mutltitasking_Gesture_Group</string>
<key>requiredCapabilities</key>
<array>
<string>multitasking-gestures</string>
</array>
</dict>
<dict>
<key>cell</key>
<string>PSSwitchCell</string>
<key>default</key>
<true/>
<key>defaults</key>
<string>com.apple.springboard</string>
<key>id</key>
<string>Mutltitasking_Gesture_Switch</string>
<key>key</key>
<string>SBUseSystemGestures</string>
<key>label</key>
<string>Multitasking_Gestures</string>
<key>requiredCapabilities</key>
<array>
<string>multitasking-gestures</string>
</array>
</dict>
5. 直接替換成以下段落
修改：
<dict>
<key>cell</key>
<string>PSGroupCell</string>
<key>id</key>
<string>Multitasking_Gesture_Group</string>
<key>footerCellClass</key>
<string>MultitaskingGestureExplanationView</string>
<key>requiredCapabilities</key>
<array>
<string>multitasking-gestures</string>
</array>
</dict>
<dict>
<key>id</key>
<string>Multitasking_Gesture_Switch</string>
<key>defaults</key>
<string>com.apple.springboard</string>
<key>cell</key>
<string>PSSwitchCell</string>
<key>requiredCapabilities</key>
<array>
<string>multitasking-gestures</string>
</array>
<key>key</key>
<string>SBUseSystemGestures</string>
<key>label</key>
<string>Multitasking_Gestures</string>
<key>default</key>
<true />
</dict>
5. 儲存檔案後就可以在一般切換手勢多工
P.S. 如不放心可以先備份原始檔
