This morning it looked like iOS 5 Beta 6 could not be jailbroken yet. Well, at least that was the case with Redsn0w. However, Windows users will be happy to know that you can jailbreak with Sn0wbreeze. Of course, this is only recommended for jailbreak developers as they ensure that their software works across those devices.
First, a few things to keep in mind. We don’t recommend doing this if you aren’t a developer. If you unlock your iPhone, don’t do it either. Also know that it is a tethered jailbreak (via iBooty). We have not tested this one out for ourselves. Please use it at your discretion and know that iSmashPhone claims no responsibility for anything that happens to your device by following these instructions.
Sn0wbreeze 2.8b1 can be downloaded here.
iTunes 10.5 and iOS 5 beta 6 are obtainable through the links we posted above. Know that the only legit way to obtain said software is to become a registered developer.
1) Launch Sn0wbreeze and click the blue “next” arrow.
2) Direct Sn0wbreeze to the iOS 5 beta 6 ipsw file. Sn0wbreeze will now identify the ipsw.
3) Once verified, it will give you a green checkmark. Click the arrow to continue.
4) You will be greeted with a prompt asking you to choose a mode. Select Expert Mode and hit the arrow again.
5) You will be given a handful of options. Click on “Build IPSW” to create your custom firmware.
6) You will be informed when the firmware has been built. You will be asked to press the “OK” button on the screen and will receive instructions onscreen for how to enter DFU mode on your iOS device. In iTunes 10.5 beta, you will have to go to your device’s settings. Hold Shift and click “Restore.” From here, you will choose your custom firmware file which sn0wbreeze created in step 5.
7) Any time you restart your device, you will have to plug it in for a tethered boot via iBooty (included with sn0wbreeze).
8) Launch iBooty, and select your jailbroken device. Once you hit “Start” the software will guide you through some steps. Once that’s done, your device should be jailbroken. Note that you will have to do this every time you reboot.
