ไม่ทราบว่ามีท่านใดลองรูทด้วยวิธีนี้ไหมครับ
ปล. ผมยังไม่ได้เครื่องเลยอ่ะครับ

1. The first step is to download GingerBreak.APK from here [unzip the archive] and save it on your desktop.
2. Once done, connect your phone to the computer and mount SD card as flash drive.
3. Now copy the APK file to SD card root.
4. After this download any good file manager like Astro File Manager from Market.
5. Once you have the file manager with you, disconnect your phone from computer and launch the file manager.
6. Now follow onscreen instructions in file manager to install the APK file you earlier copied to SD card root.
7. Once the APK installs, it will execute the exploit remounting /system read/write and will root your phone along with installing SU.

And there you have it! Your Android phone upgraded to Android 2.3.3 Gingerbread is now rooted. For all those who weren’t able to run this, please head to the official XDA thread here for troubleshooting and other information. As this is the first version, so error expectation is high. However we will keep an eye on the development and update this post once there is any further information or a newer version available.
