The options for VoIP calling on the iPhone are expected to continue expanding with both Skype and Truphone expected to join a growing list of VoIP apps for the Apple handset.

Truphone already provides an app for the iPhone which enables users to make low-priced international calls via the GSM network even when the smartphone is not connected to the Wi-Fi network.

But the company announced at the recent Macworld 2009 that callers will soon be able to use Truphone to make and receive Skype calls and instant message.

Not to be left out, Skype itself announced at CES that it is also developing a native client for the iPhone.

The subsidiary of eBay said that a version of its Internet calling and instant-messaging software is available for Google’s Android cell phone platform as a free download – and an iPhone Skype program is expected shortly.

Fring also has an app that you make Skype calls using the iPhone.
