You can jailbreak ios 5.1 tethered on iPhone 4, 3GS, iPad 1, iPod Touch 4G, 3G using latest version of RedSn0w 0.9.10b6. I have given below the download links for redsnow 0.9.10b6 and complete step wise guide to jailbreak iPhone 4, iPhone 3GS, iPod touch 4G, iPod Touch 3G and iPad 1.
Before continuing you have to note that:
- This is a *tethered* 5.1 jailbreak for non-A5 devices (i.e. other than iPhone 4S, iPad 2&3) that means each time you need to reboot your idevice you will need to use redsn0w and select the option of “Just Boot” as mentioned in below jailbreak tutorial. Otherwise your Safari and Cydia apps will not work/launch.
- Similarly If you want to use ultrasn0w for your carrier unlock, be sure to use a custom IPSW to update to 5.1 first. You have to use redsn0w for generating custome ipsw “Custom IPSW”.
- This jailbreak is will become automatically untethered if your device has old-bootrom 3GS.
- iBooks is not working until next update of redsn0w is released
