Should I buy the iPhone 5 or wait for the next one?

I have made up my mind that i want an iPhone and no other phone so please do no recommend anything else.

Next iPhone is rumoured that it might come out in oct-nov

Actually I've heard the end of the summer. I'm waiting for the new one (it couldn't hurt. My iPhone 4 works fine).

Buy the iphone 5 bc it will be awhile b4 the iphone 6 comes out but its better to wait for the I5s
