Would it be safe to upgrade to ios 7 now?

It's supposed to be the gm release (not the beta). I want to install it on my iPhone 4S. Would it be okay to install this? I don't really want to wait, but I paid a lot of money for my iphone last year and i really do not want to wreak it. I know what I'm doing (I've done jailbreaks and stuff before) but would this safe or should I just wait?

It should be perfectly safe Rebbecca if you know what your doing. However it is good to wait until things are tried and tested to a certain degree just to be on the safe side.
Its your call but if I were you I would give it a few days at least.
