With the release of Pangu 1.0.2, Cydia and its Mobile Substrate plugin are now fairly stable. With this, manual resprings from OpenSSH are no longer needed. If you have jailbroken 1.0.1, there is no need to restore. Head over to the "Changes" tab and hit "Update" in the top left. Now this is released, many tweaks and themes will be added to iOS 8. In the mean time, not many Cydia apps/addons are available. Keep an eye here for more info soon.
