Would a jailbroken 3G iPhone be able to use iOS-7?

I have an iPhone 3G and before I buy a newer iPhone, I was wondering if I had it jailbroken, if it would be able to use Apples newest operating system iOS-7.

Not possible

No, the best you could do is jailbreak it and get a theme that would make it seam as if it had the newest OS but other than that no.

Nope. Wait til the ios 7 jailbreak comes out
