For those of you holding your breath for Skype to work over AT&T's 3G network, you will soon be able to relax as Skype has told TiPb it's only a matter of time. From their blog:
blockquote>You may have seen other apps offering calls over 3G, but we’re holding ours back for a little bit longer. Why? So that we can give you the very best audio quality we can. When our 3G-capable Skype for iPhone app is released, it’ll let you make calls in wideband audio, giving you greater clarity and fidelity – because that’s what you expect from Skype.
