Sometimes the upgrade date can be moved up if you pay a lot per month because of a larger plan, unlimited sms/data, etc. You pay off your subsidization quicker.

Yes-- i pay $250/mo on my plan (international data & etc) and also bought the iPhone4 subsidized day 1, and my message says I am eligible for an upgrade now.

Ah, that could be it. My girlfriend is on my plan as well, so I'm paying a bit more than your average customer.
