I've read the details. However I'm going with the notion I can't take their word. Maybe you can take them up on it. I just have a feeling they are going to do it across the board to all unlimited data users claiming "network congestion". Do I want that to happen? No way! Verizon is the best in my area, but I have to face facts this is a money maker move on their part. Using this excuse to move you off the unlimited data plan.
Doubt it. Verizon doesn't want to waive their ETF fees if you used a subsidy upgrade.
They lose nothing if you are out of contract.
