While we have already seen a number of messenger applications for the iPhone, (both in version 1.x and 2.0) that offer Skype services; we are yet to see an official app from Skype for this purpose. However, there is now an official confirmation from Skype that an official App is underdevelopment. The quality that an official Skype app would recommend is certainly better than what the IM+, Nimbuzz, Fring and others can offer.
Mobile internet is booming, messengers on smartphones, are doing well, and Skype firm wants a hefty chunk of VOIP to find its way. Skype leads the desktop when it comes to internet phone, not too long before mobile takes over desktop itself.
We believe the Skype App to be free via the Appstore whenever it releases.
