Did you Install Coolbooter?

For many us, it is not important to run  two different firmware versions on an iOS device. We all want stability while using our jailbroken devices. Nevertheless, it is a major achievement for iOS hackers. This might give developers the opportunity to dual boot iOS and Android in the future.

If you have an older device lying around, feel free to install Coolbooter on that. Even though it’s quite safe, I wouldn’t recommend that you install it on your main device.

Hopefully, the developer will add support for more devices in the future. Even a triple boot feature isn’t off the table yet.
