We just found something very interesting.  When you install Skype on a 3.0 developer preview iPhone, you can use AT&T’s connection to make and receive calls.  It even works pretty well over EDGE.  Skype treats AT&T’s WWAN like a Wifi connection.  I did a quick video and posted it below:

Update:we just made a Skype call over 3G to another 3.0 iPhone using 3G.  The sound quality was as good, if not  better than normal AT&T.  (Thanks  Josh!!)

BTW, if you are commenting that it doesn’t work for you and you don’t have the 3.0 developer preview, you are missing the whole point of this post.
