Anyone else worried we will run into problems again this year trying to use the Upgrade Program to go from iPhone 7 to 8? I signed up for the upgrade program for the first time last year when I bought my 7 Plus. However I remember all the supply issues Apple had specifically for the current Upgrade Program members. Considering the rumors on supply constraints for the next gen iPhone, how do you think things will go for the Upgrade Program members this year? I would think (hope) Apple learned their lesson from last year and will prioritize customers upgrading. Thoughts?
