before 3.0 with the notification system or some other way to keep applications running in the background, this, like all the other IM applications on the iPhone/touch, won't be of practical use. Talking in Skype and recieving a traditional phone call? Skype call drops. Skype quits. Talking in Skype while surfing the web. Nope. It's either Safari or Skype. Tapping on a link in a Skype chat? Sure, but you'll go offline doing that (Skype closes before Safari opens). Waiting for a call at a scheduled time? Sure, but don't think about browsing the web or even just browsing your music library to play something as all these actions will quit Skype. Nah. IM and even more so VoIP are totally unpractical on the iPhone. 3.0 will bring some alleviation with the background notification service as you'll at least know when someone tries to call you, but it's still nowhere near usable. At least for me. And that's this "changes the game"? There are already a bunch of - even Skype compatible - VoIP applications out there for the iPhone. They just didn't take off due to the reasons stated above.
