"Nokia has made Skype available as a free download from its Ovi online store. It will mean that for the first time Nokian's Symbian-based smartphones will get fully functional cheap internet calls.
The Skype for Symbian service allows users to make free Skype-to-Skype calls internationally, save money on regular international calls and to share files including pictures and video. Of course you have to be talking to other Skype users, but all it will cost you is your data connection." source
