Now that the iPhone SDK seems to allow for 3G VoIP, it looks like the floodgates are beginning to open. Joining the ranks of iCall in this somewhat uncharted territory is Fring. Same deal as the previous one, the ability is already inherent in the current build, and now that the restriction has been lifted, users can simply place calls as they usually do through the service -- yes, that includes Skype calls -- only now not tethered to the nearest 802.11 cloud. As for the native Skype app, last we checked it was still not working. But it's only a matter of time.
