The 4G upgrade site is now live. Motorola Xoom Upgrade - Verizon Wireless I submitted a request to get mine upgraded and they have already sent me an overnight box. They are also throwing in a standard dock in for free if you get it in early enough.
That's the plan. I'm going to ask my fedex driver if s/he's going to be in the area for a bit if they'd mind stopping back and doing a pickup. If not, I'll have to drive to the nearest fedex drop off point.
