Excuse me but NONE of these people have the 8820! Until you see them on eBay with images of the actual retail box, they are not out on the streets for sale. These people are hoping you are so desperate that you will pay way over retail and then wait for them to deliver while you local ATT store is selling them for way less.
For me the REAL way to tell if the 8820 is actually at the stores is REAL images of the little beast in the actual retail box. Looks like none arrived at the stores on opening day, maybe today! Just keep you eye on eBay and it will tell the story!
