Notes:
- In case you got Error 10, then you’re not using iTunes 10.5 beta 7.
- In case you got other Errors, then you didn’t put your device in DFU mode. Just use iREB to put your device in PWN DFU mode.
- iOS 5 beta 7 is tethered only jailbroken, so you’ll have to use iBooty (Sn0wbreeze 2.8b7 downloads it in the same directory of your custom IPSW) everytime your iPhone is rebooted to get Cydia installed again.
