Skype have confirmed
that a version of their VoIP software for the iPhone will be released tomorrow, Tuesday March 31st. Rumored to be in the works last week, the free iPhone Skype app will use the smartphone's WiFi connection to make free Skype-to-Skype calls or ring landlines for around 2.1 cents per minute.
What won't be possible is VoIP over 3G. This is, according to Skype, due to Apple's App Store limitations; neither Apple nor AT&T would comment on the situation. In contrast, the Android Skype application - launched back in January
- will work over either 3G or WiFi.
