1. 需要 root 權限
2. 建立兩個 FAT32 主要分割區
3. 要放 APK & Devlik-cache 的分割區是 第二個 FAT32 分割區
4. 安裝 Link2SD，第一次執行後會自動產生需要的 Script，會提示重新開機
5. 重開後再開啟 Link2SD，一切順利後就可以手動將 APP 移到 SD 卡上的第二個 FAT32 了!!
=== 2011/03/20 Update 以下註一至註三於 1.5.5 版後已不再需要!!!! ====
註一 Android 2.1 或更早版本在 APP 移過去 SD 後會暫時消失，重新開機後就會出現，移回來也要重新開機
註二 移去 SD 的 APP 會在 Market 中 "我的應用程式" 中消失，可以先將 Market 程序強制停止再使用 Link2SD 的 "Market Fix" 功能修復
註三 使用 "Market Fix" 修復後，若 "我的應用程式" 仍未出現移動的 App，可以隨便安裝個小程式再移除，Market 就會強制更新，移動過的 APP 就會出現了。若從 SD => ROM 則不須此動作。
=== 2011/03/20 Update 以上註一至註三於 1.5.5 版後已不再需要!!!! ===
這是我第一次看到方便操作且支援 FAT32 的 App2SD 程式，請大家幫作者拍拍手!!
有新進度我會 Update 在這裡，有問題的可以自己上 XDA 發問，或是集中在這篇文章討論囉，祝大家用的愉快!!
