Is their a ios 7 jailbreak for the iPhone 4?

I really need my phone jailbroken my sis updated it but it's a iphone 4 any betas or something

Well, it's probably for the best. I suggest you stay unjailbroken.

There's no untethered jailbreak for your device at this stage. It is coming, so just hold tight.
