Truphone, the mobile VoIP application, has added Skype features to its free Apple iPhone and iPod app.
iPhone and iPod touch users can now Instant Message Skype contacts, make calls to Skype users on your contact list – although this version does not support Skype Out calling - and receive calls from other Skype users.
If you are in Wi-Fi then all calls and instant messages will be completely free says Truphone, while those without access can use Truphone Anywhere.
Truphone also added AOL Instant Messenger support, Truphone customers can now keep in touch with over 800 million addressable accounts for free.
Truphone already offers integrated Google TalkTM, SkypeTM, Windows Live MessengerTM and Yahoo! Messenger support.
"Our goal is for mobile phone users to be able to reach any contact in their address book or on their buddy list, in a low cost way, at any time, using just one application," said Geraldine Wilson, Truphone chief executive.
"Today's announcement means that iPhone and iPod touch users gain a great way to stay in touch with AOL Instant Messenger users."
