I have a brand new iphone 7 coming next week after my trusty iphone 4 (don't laugh) is getting put out to pasture after almost 5 years of jailbroken happiness. The phone comes carrier unlocked but apparently locks to the carrier of the first sim inserted. Is there any way I can somehow stop it locking to this sim? Also while I am unsure which ios the phone will come preinstalled with, if it is ios10.1.1 or below will I be able to activate it without being forced to install 10.2 via itunes? I'd like to obviously jailbreak it and wouldn't want to ruin the chance just by activating the phone for the first time. I've read that itunes has to "sign" for the ios and this no longer works with 10.1.1 Thanks for any help.
