Iphone 5 jailbreak iOS 7.0.4?

Any problem I put the jailbreak on my new iphone 5

Can you maybe say the actual question, what do you mean? Yes it jailbroke my 5s it's very though I have jailbroken mine since iPhone 4 and have had every single phone and has always been as fun lol

No problems. Don't update to apple 7.1 which is due out soon. As for the jailbreak of 7.0.4. Use evasion

Over the air updates seem to be facing issues. If you did an OTA to get to iOS 7.0.x, you might have to do this:

Take a full backup of your iDevice in iTunes
Now, do a fresh restore via iTunes and upgrade to iOS 7.0.4
Then, restore the backup
Finally, proceed to jailbreak.

Make sure to read this tutorial first before you take any steps:
