It was time to dump US Cellular (who I learned you should never have as a carrier if you travel outside Wisconsin), so this morning I went to Verizon.
Moved our 4 lines over. Pre-ordered 2 iPhone 7+ models. By 10AM CDT, there were models with NOVEMBER estimated delivery dates. By choosing the 256GB models, we only have to wait an extra week, although they cost an extra $100 each. The Jet Black would've been delivered sometime about Thanksgiving.
This was the first time since the original iPhone I waited 2 years to replace a phone. Still works fine, although battery charging has been a bit odd lately.
