With the Skype app, users can make free Skype-to-Skype calls, and call phones at Skype’s rates over WiFi or 3G (except US). Skype can be run over GPRS or EDGE but is not recommended due to slower speeds.
Though voice call is available, there is no sign of video calling. However another good feature of this app is that it can sync friends on Skype with your contacts on the phone.
Skype which is already available for iPhone and Symbian phones has been highly demanded on Android. Skype for Android has an edge over the iPhone version due to a better notification system.
