iPhone 3GS升级iOS4.0并越狱

by on 七.04, 2010, under iPhone

手上有一部港行的iPhone 3GS,虽然是41周前的,但是因为之前用了Spirit,所以无法直接使用自制固件了。

今天发现一个Cydia上的软件,可以解决这个问题。

前提就是您必须在iPhone 3GS的(旧的bootrom)和Spirit 越狱3.1.3

*打开cydia,并添加源 – > http://repo.woowiz.net
*现在搜索 – > Spirit2Pwn。
*安装Spirit2Pwn和重新启动设备。

现在,Spirits越狱的机器可以接受任何自制4.0固件了.
