As is the case with every new iOS 5 beta release so far, jailbreak tools such as redsn0w and sn0wbreeze are updated to support it. Keeping in line with this, sn0wbreeze 2.8 b5, the popular custom firmware tool for Windows, has been released which jailbreaks iOS 5 b5 on iPhone, iPad and iPod Touch. We’ve compiled a really simple and helpful guide to get you started on jailbreaking your iOS 5 b5 device with sn0wbreeze 2.8 b5.

Supported devices:

  • iPhone 3GS [New bootrom]
  • iPhone 4 [GSM
  • iPhone 4 [CDMA]
  • iPad 1G
  • iPod Touch 3G

Note : You obviously need to be a developer to have iOS 5 b5 installed on your device so follow this guide only if you’re technical enough. Else if you’re iOS device goes boom, it wouldn’t be our fault.

  8. Now you’ll be presented with different options. For the sake of simplicity, we will follow the simple mode in this guide. If you really want to tinker with the firmware to your liking, you can use the expert mode and pre-install your favorite Cydia packages right from within sn0wbreeze. This is helpful as whenever you will restore this firmware to your device, it will always have those packages installed. But since the packages can also get outdated so you might have to update them later. You can also use custom logos if your iOS version is supported or change the disk space used.sn0wbreeze 2.8b5 for iOS 5 b5 6wtmk

  10. Now, the sn0wbreeze part is complete. You will have to put your iOS device in DFU mode to restore the custom firmware to it. This can be done connecting it to the computer and turning it off. Hold the power button on your iOS device for 3 seconds. Now, without leaving the power button, hold the home button for 10 seconds. Then, leave the power button but keep the home button pressed for 30 seconds. Windows should make a sound when it detects the device in DFU mode. iTunes will also tell you when it detects the device in this mode.
  11. While holding down the shift key, click on the restore button and point it to the custom firmware you just created. It should be on your desktop.iTunes 10.5 b5
  12. Once it’s done, your iOS device would have a jailbroken firmware. But since this is a tethered jailbreak, you will need to use the iBooty utility to boot the device. Just re-enter DFU mode on your device and run iBooty ( this will be generated after your custom firmware is created ). Once booted, you can enjoy your jailbroken device!
