So I was one of "those" who jumped before looking, buying the Hero, finding out it did not have Skype and being like... WTF?! So I figured out what SIP was all about and also figured since Google Voice works with Gizmo that that would be a good thing. However calls with Gizmo and Google Voice are so poor in quality that it's not a viable solution. I'm wondering if there really is such a thing as quality SIP through the Hero. I'd be willing to pay a lot of money for a quality SIP provider, if I could get a clear data call through my phone on wi-fi. Are all SIP providers created equal?
