Skype users can now make calls using the VOIP service over a cellular data connection. Previously, calls could only be made over a Wi-Fi connection through the app. Apple had revised its Program License Agreement earlier this year to allow apps to make VOIP calls over cellular data networks, opening the door for Skype and other similar VOIP apps such as iCall and Fring, though Skype is a little late to the party relative to other apps that received this feature sooner.
As a temporary promotion, the Skype app’s description notes that “Skype-to-Skype calls on 3G are free until at least end of August 2010, after which there will be a small monthly fee (operator charges for data will still apply).” The small monthly fee mentioned has not been described in more detail yet.
The updated Skype app also works on the iPad, enabling 3G iPad owners to use their shiny new Apple tablets for phone functions even when out of range of a Wi-Fi network.
