iPhone users will finally be able to take advantage of Skype 2.0, with 3G calling, according to a report. But after August they'll have to pay for the privilege of Skype-to-Skype calls with the new service.
Gizmodo reported the iPhone-ready service and a "small monthly fee" associated with it (along with operator charges for data). Gizmodo also noted that upgrades include near CD-quality sound for Skype-to-Skype calls, faster start-up time, a better call-quality indicator, and quick access to the dial pad via the iPhone home screen.
AT&T cleared the way for Skype on the iPhone late last year, when it tweaked its network to allow VoIP calls.
Update, May 31 at 6 a.m. PDT: In a separate report, PC World reported that Skype had not yet decided how to charge for the 3G calls and that the fees would kick in "after the end of 2010." That report also said the new 3G service applies to the iPhone, iPhone 3G, and iPhone 3GS; users of the second- and third-generation iPod Touch can also use the Skype service, but only over Wi-Fi, since those devices lack 3G, and only with a compatible headset with microphone.
