3g to 4g $100 mail in rebate code "CH4GE" is valid (for those skeptical like myself), and expires December 31st. I had the CSR note it on my account, and it can be redeemed either through *611 telesales, or in a Verizon Corporate Store.
I called *611 and asked them about the "Midwest regional 3g to 4g $100 off rebate", they knew nothing. Gave him the code and he instantly found it, gave me the details, and was on my way.
Also, I had 2 CSRs CONFIRM that the device was planned and supposed to launch Friday the 9th, but due to the outage, it was pushed back. They wouldn't say when it was supposed to launch, but my local store said the 15th.
To summarize it all up: Call *611, press 0, say "upgrade", then ask about the "Midwest regional 3g to 4g upgrade promo for $100 off rebate." They will search, most likely not find anything, then give them the code "CH4GE". They will find it, and tell you it must be applied when you purchase the device, but you can have them note your account with the code.
Just like that, the Nexus becomes even better
