It hasn’t even been officially released but a public jailbreak of iOS 5 Beta 1 has been released. This comes after iOS 5 Beta 1 was jailbroken in under 24 hours of it being released. You can jailbreak iOS 5 now but it is tethered which means that you will have to plug your iDevice into your computer when it restarts or if you want to turn it off and on. If you have an iPhone 4, 3GS, iPad 1st Gen, iPod Touch 3G or 4G then you can tether jailbreak. To do this you need a Mac as far as I’m aware and download Redsn0w 0.9.8b1 here.

To complete the jailbreak just follow the on-screen instructions which are easy.

To restart in tethered mode just follow these steps:

1. Start again Redsn0w.
2. Select “Just boot tethered right now”.
3. Reset the iPhone in DFU mode.
4. Wait for the restart of the iPhone.
