Here’s the Skype app, delivered on Tuesday as promised.

In their own words:

With Skype on your iPhone or iPod touch, simply sign into Skype from any WiFi zone, and call friends and family on Skype totally free.

See who’s online and instant message them.

Sign into Skype via 3G, Edge, GPRS or WiFi and check who’s online – then instant message them whenever and wherever the mood strikes.
