Should I Update My Iphone 4 To iOS 7 Or Keep It Jailbroken On 6.1.2?

I Really Want iOS 7(Even Though Its Still In Beta), Because The Jailbreak Is Taking Up Alot Of Space On My Phone. I Also Don't Use My Jailbreak Much And I Really Like iOS 7.

I think you can get an iOS 7 beta theme on dreamboard. It would be almost exactly like it. I have dreamboard themes like android and windows 7, because ios 7 really isn't my thing, but I would recommend deleting some tweaks and installing the beta version for dreamboard. Best of luck!

Upgrading to iOS 7 is totally worth it, but make sure your UDID is registered on a site like http://www.instantudid.com/ or you'll run into activation issues.
