About the guy asking if he can upgrade early, definitely keep trying and your luck will pan out. Crazier things have happened...
Like with my Droid incredible. Starting around June, it really started to act up and would constantly overheat. Internet? Give it about 5 minutes before rebooting. Navigation? Maybe a minute. Games were also rough, and not to mention, that it would get caught in a power cycle and constantly reboot. I would have to give it a battery pull to fix it. Now, every so often, this battery pull would pretty much delete all app data from my phone. I would be stuck with constant force closes and would have to delete and reinstall my apps. All data regarding these apps were gone as well (I probably played through Cut the Rope like 3 times).
I called around July and they said there was nothing I could do since it was out of the 1-year MFG warranty. I cited that many people were having problems with this exact thing and again, no dice. I called VZW, HTC, and HTC's warranty center with no luck.
The Galaxy Nexus couldn't come soon enough for me. I was praying the Galaxy S II would come to VZW to upgrade to (I've had the upgrade available since late July), and that avenue was closed. I had to restrain myself from getting the Bionic since I was currently working with a crippled phone.
On a whim, I called VZW again on Friday night (at around 10PM), and talked with someone for about 45 minutes. I explained my problems again, was polite, and she said she could send a certified pre-owned for a cost. I said I would just wait for the Nexus, and she suggested an upgrade, while I also declined. All hope seemed lost, but at my darkest hour and about to give up, she said let me check one more thing. I was put on hold for almost 5 minutes, and when she came back, she said after talking with her supervisor, she would send me a replacement at no cost, despite it being out of warranty for almost 3 months.
I got it on Monday, and am loving having a functional phone again, which really helps take away the pressure and anxiousness for this to drop. It also gives me some renewed confidence in Verizon and that there really are people in the company that care about their customers.
A bit of a long-winded response, but I am confident that if you keep calling (especially after its released), you'll be able to upgrade early.
