Apple released iPhone OS 3.1.3 recently to improve and fix a few issues with iPhone OS 3.1.2 and the iPhone Dev Team recently released their updated redsn0w software to jailbreak iPhone OS 3.1.2 but an unofficial feature of Redsn0w 0.9.2 is the ability to also jailbreak iPhone OS 3.1.3. That said, lets get jailbreaking that device of yours.
In this tutorial, I will show you how to jailbreak iPhone OS 3.1.3 in the same way you would jailbreak iPhone OS 3.0 with redsn0w 0.9.2.
Please follow these instructions clearly and you’ll be a-o-k. Now, before we begin you may notice that we use the iPhone OS 3.1.2 IPSW to jailbreak our iPhone OS 3.1.3 device, this is no mistake. When you get asked to select the iPhone firmware you have installed then choose the iPhone OS 3.1.2 IPSW. Please make sure you have updated your device to 3.1.3 by either updating officially via iTunes or restoring via iTunes. Keep in mind that restoring your iPhone will erase your iPhone’s content. In this tutorial we use Redsn0w version 0.9.2
Note: We are not responsible if your device blows up in the middle of the jailbreak process or if your device doesn’t turn on after using this. Use, strictly, at your own risk!
- First is first, download redsn0w 0.9.2 here (for Windows) or here (for Mac OS X)
- Second, Download iPhone OS 3.1.2 (to Jailbreak 3.1.3) or whatever firmware you’ll be using to jailbreak – here
