The new iPhones will without a doubt have the gm version even if a new patch comes out since they've already been loaded on the phones. I know this for a fact because I work retail for one of the four major carriers. I activate at least 10-20 iPhones a day and when 6.1.4 came out, every new iPhone had 6.1.3 on them. The customer had to go home and update to 6.1.4(which they never did) because we do not have wifi in our store so even if they do patch it it's highly likely many customers will not update.
