I installed iOS 11 GM on my iPhone 7 Plus and so far so good. I was curious about this "Unlimited Updates" switch in the Photos cellular settings. It says turning it on may cause me to exceed my "quota". Anyone know exactly how much this limits cellular data usage by Photos? It'd be nice to have photos upload over cellular while traveling, and having a throttle in place to prevent too much data plan usage would be great, but the phone doesn't say how much this limits it.
