How to jailbreak my iPhone 4s with iOS 7?

I have updated my iPhone 4s' software to iOS 7 and it lost cydia. How can I get it back?

There are no jailbreaks for iOS 7.

IOS 7 is a completely new operating system for the idevices so I'm not surprised that there isn't one, in fact, I realised that I couldn't get it for my 3GS so it must be pretty new technology. Anyways I think the experts would come out with a jailbreak sooner or later

At this stage, there's no jailbreak for iOS 7 on any device.

One is coming, so be patient.

Jailbreak is not available for iOS 7 yet. Do not upgrade to iOS 7 until someone releases Jailbreak tool. Official unlock service is available on the net, you can give it a try.
