There continues to be a lot of availability volatility with the iPhone 15 Pro Max. AT&T is continuing to see their availability situation improve with five of eight memory/color combinations mirroring that of T-Mobile. It looks highly likely that iPhone 15 Pro availability issues will be cleared up prior to the start of November.
The predictability that is coming into focus for the iPhone 15 Pro is not being mirrored by the iPhone 15 Pro Max. There is a higher probability of having a memory/color combination move out vs. move in. We do not have prediction on when things will stabilize for this SKU.
