The jailbreak is mainly a developer focused release to help them update all their tweaks and apps for iOS 8. According to Team Pangu, Cydia will be added in a future update to the jailbreak.
Saurik has done a great job to make Cydia compatible with iOS 8 and release it to the public in a short period of time, but you'll need to install it manually.
In conclusion, here's what you need to know :
- iOS 8 Jailbreak is available.
- It's in Chinese.
- Most of the tweaks don't work.
- Doesn't come with Cydia.
- Only for Windows.
So those of you who don’t feel like fooling around with the file system, I highly recommend to wait for the final version that will work perfectly.
Very seriously, going through with this might not be the best idea you ever had.
