Jail Breaking iPhone 5 iOS 7?

A lot of people are probably already asking this question, but I would like to jail break my iPhone 5 which has iOS 7.0.4.Is there any way to currently jail break it or get cydia? All I really want is to be able to have a gif file as my wallpaper, (lolz). I really don't mind downloading things to my computers and what not, I just really want to jail break it.

Also, if I do jailbreak it, is there a way to unjail break it where I can keep my data such as text and etc and not use one of the latest backups?

Unfortunately, there's no jailbreak for iOS 7, for any device except the iPhone 4. Yet. The devs are working very hard to perfect the iOS 7 jailbreak for public release. To keep yourself updated on the progress of the jailbreak, visit this site:

jailbrea.kr

That site is run by those devs currently working on a jailbreak.

To answer your second question, yes, you will be able to unjailbreak your device if need be. However, by doing so you will be doing a complete restore of the device and therefore would be left with no choice but to restore it from a previous backup. So texts would disappear. Although, I do think there's an app that exists in your App Store that has the ability to back up text messages. I could be wrong about that though.

Hope this helps.
