HTC EVO 4G :: Phone Won't Charge After 2.2 Update

I haven't seen this issue reported anywhere else so here it goes. I just updated my phone to froyo last night and had no apparent issues. When I woke up I noticed that despite charging the phone overnight the battery was dead. I was able to start the phone up with the charger plugged in. This is when I found out that the battery won't receive a charge. I have tried using the standard plug as well as plugging the usb cable into the computer; no dice. The lightning bolt on the top right of the screen is there, but the green slice on the battery that constantly recycles is stuck. I tried a master reset on the phone and that didn't work either. Anyone else encounter this issue? Any ideas how to fix it? I bought my phone at Best Buy, and of course they are all sold out in the area, so it will be a major pain getting a replacement (I'm within the 30 day window).
