I plan on switching from AT&T to T-Mobile. Usually when you are porting an existing line to a new carrier, you get really good promos since these are considered very valuable. T-Mobile has a deal where my wife and I can get an iPhone 11 for free but I decided to hold off until this year's Black Friday for the iPhone 12 release. I just want to make sure I am making the right decision in waiting for the first major redesign.
