Skype App Updated to Allow Voice Calls Over 3G
In the past, AT&T has restricted these applications to Wi-Fi networks only to avoid piggybacking on their 3G service. AT&T, however, changed their position on this back in January but it has taken this long for Skype to release an update that supports this feature.
Skype indicates that this feature is free until at least the end of August, but at that time a small monthly fee will be initiated. It's not clear how much they plan on charging.
