That does seem to fall in line with (today's) rumors about the iphone actually hitting verizon at the end of January. We'll all know about that rumor tomorrow though.
Right now it feels like the Atrix is riding high on the hype from lots of major news outlets, it seems almost a shame to let some of that cool just to ride out an iphone announcement, especially since most editorial sources agree that this iphone will be just like the iphone 4.
On a separate note, does anyone know if 3rd party retailers stock phones at the same time that AT&T does? Or does it sometimes take a week or two to reach them? I honestly have very little experience buying phones from anywhere other than carrier stores or online.
