IPhone 3GS Jailbroken, then updated, and now not working

I bought a jailbroken iPhone 3GS and then I made the mistake of updating it to iOS 6.It's now stuck on the activation screen. I spoke to someone and they said that once iOS 6 jailbreak comes out it will work again, are they right?

Yes luckily the jailbreak just came out! It will take you 5 min! I recommended that you update to 6.1 via itunes and usb instead of doing it over the air. Here is a link make sure to back up your phone and read/follow each step carefully. Good luck and enjoy your phone again!
