I'm thinking of returning my 6S and getting the 7. I have a JB 6 to hold me over in the meantime and I haven't owned a new current iPhone in almost 3 years.This is kind of why nobody should update just yet, At no point was it said it will be releasted

Its best to hold tight, what ever you do, don't update if you are already jailbroken until its out if ever
