I don't know how any of you have been able to upgrade as early as 13 months. I have always had a every 2, and the earliest I could ever upgrade was 20 months, and I've been on Verizon for years, back when they had the america choice or whatever plan it was called. So this doesn't affect me at all if they keep it at 20 for early upgrade.
What's the cost of your monthly plan? In the past, it had to be over a certain amount to qualify for the early upgrade. Maybe you didn't qualify for early upgrade.
