The developer of the sn0wbreeze tool for jailbreaking iOS devices and installing custom firmware has updated the software to work with iOS 5 beta 6. You can use sn0wbreeze 2.8b6 to not only jailbreak the latest beta version of iOS — but like the last version of sn0wbreeze, version 2.86b also lets you install ioS 5 beta on an iPhone, iPod touch, or iPad even if you don’t have a developer account.
Normally you need a developer account which costs $99 per year to install beta versions of iOS. Sn0wbreeze lets you get around that — and also disables the expiration date on the beta so you can keep using it indefinitely — although you’ll probably want to upgrade to the full version of iOS 5 once it’s released. There are still some unfixed bugs in the beta version.
If you jailbreak your device using Sn0wbreeze 2.8b6 you’ll have a tethered jailbreak, which means you need to connect your mobile device to a computer and run the software again if you reboot your iPhone, iPad, or iPod touch. If you have an iPhone 3GS with an old bootrom you can also perform an untethered jailbreak.
