I have done this at the 90 day mark before my contracted ended, the last 3 times I upgraded. Like I said, log into your online account with Verizon and check your phone, it will tell you if you are ready for an upgrade. My guess if you have 2 lines with different renewal dates, they just pulled the one or main line and didn't look at the line you are looking to upgrade. If you don't want to do this, call or stop into a Verizon store, they can tell you if you can upgrade yet or not.
