If you have upgraded your iPhone or iPod touch to the latest firmware 3.1.3 without giving any heed to the repeated cries from the dev-team and the others that the updated firmware will create problems while jailbreaking and unlocking it. Luckily, you can now Jailbreak and Unlock your updated iPhone or iPod touch OS 3.1.3 with redsn0w 0.9.4 OR in this case, with Sn0wbreeze v1.4 which the ih8sn0w team released just a day ago to enable jailbreak for the updated firmware.
Sn0wbreeze allows users to upgrade from a jailbroken iPhone OS 3.1.2 or lower to iPhone OS 3.1.3, which was released few days back to fix some minor bugs. Sn0wbreeze is a tool for Windows that will jailbreak your iPods and iPhones, setup custom boot logos, activate your iPhone, root partition size, build custom IPSW, and more! I downgraded an iPhone 3gs to 3.1.3, however, I want to change the bootlogo. I heard if you make a NOR only ipsw you can do that, but i cant make the option show up in sn0wbreeze? Does anybody know if i need a specific sn0wbreeze version for this or what im doing wrong? A Windows.NET GUI Wrapper for xpwn.
