Post your favorite jailbreak tweaks/beta improvements for iOS and screenshots here. I'll update this post with a link to the newest jailbroken iOS release. Right now it is iOS 8.4 which can be retrieved here:

To install this you need to hold left shift and click restore on iTunes. From there simply click the ipsw.
And can be jailbroken with TaiG 2.3.1, found here:
You must be running Windows (for now), and be using iTunes 12.0.1 as newer versions break the exploit. 12.0.1 can be found here along with a downgrade process:

From here on just run the utility with admin privileges and it should be straight forward. If you need just ask (although if it is a bigger issue a thread or PM would be preferred).
I will not be posting how tos on updating to betas unless they are public as that would violate Tek Syndicate's rules on software rredistribution due to the betas being specific to those who purchase Apple's developer license. If you want a tutorial PM me.
