如果你有Iphone 3G 或者 3GS，但又不敢自己解碼。如果你是AbleSky用戶，來清華科技園，幫助你解碼。大約需要時間30分鐘。
來之前，與本人先約定。

Iphone OS 4.0 是最新的操作系統(tǒng)，非常好用！

破解 Iphone 4.0 3G， 3GS, 具體步驟。

1. 更新到 4.0， 用Itunes。

2. 下載 Iphone 4.0 軟件。

3G： http://appldnld.apple.com.edgesuite.net/content.info.apple.com/iPhone4/061-7436.20100621.58Yt4/iPhone1,2_4.0_8A293_Restore.ipsw

3GS: 從 http://www.apple.com 找

3. 越獄！用 RedSn0w （軟件見附近）。

4。 解碼 using UltraSn0w：

You can unlock iOS 4 on iPhone 3GS 3G if you abide by the tutorial.

Function 1: Your iPhone 3GS 3G should be running on jailbroken iOS 4. If this is not the case, you can jailbreak it using redsn0w 0.9.5.

Function 2: Run Cydia on jailbroken iPhone and then navigate to “Manage” tab at bottom.

Function 3: Touch “Edit” and then “Add”. You will be asked to enter a URL for repository source. Enter “http://repo666.ultrasn0w.com” and finally “Add The Source”. Leave the rest for Cydia as it will update the sources.

Function 4: Now search “ultrasn0w” in Cydia and install the application. The latest version of ultrasn0w would be 0.93. ultrasn0w 0.93 will unlock iOS 4 on iPhone 3GS 3G.

Function 5: Restart iPhone 3GS 3G and you can use iPhone with any carrier.
