Looks like TaiG just released a jailbreak for 8.1.1 (and 8.0,8.1,8.2beta). Best to wait a few days just in case
TaiG was part of the controversial iOS 7 jailbreak from the Evad3rs. The jaibreak included the TaiG ‘app store’ for cracked apps by default in China. Following an outcry from the community the evad3rs responded by updating their jailbreak tool to remove TaiG. They also posted a letter to the community saying "we are deeply sorry and embarrassed about the piracy that was seen today".
It’s unclear what comes bundled with the TaiG jailbreak that has just been released. We are looking into it and will update this article shortly. It’s also unclear as to who is actually behind the exploits used for the jailbreak.
If the jailbreak proves legitimate and safe, we will be posting tutorials shortly!
It appears as though the jailbreak is only for Windows at this time.
