The free Fring for iPhone is a compelling VoIP caller and multinetwork chat app in one. Tap over to the add-ons section to talk to friends using Skype, SIP, and Windows Live Messenger (MSN), Google Talk, and ICQ's protocols. Like plugging a headset into the PC, Fring's app spells cheap calls to international contacts. Beware though, you'll need a strong Wi-Fi connection to make or receive VoIP calls.
In addition to stretching out your vocal chords, Fring can open conversations for the IM networks above, as well as for AIM and Yahoo. Signing into Twitter from Fring lets you easily read your friends' feeds and update your own status.
While Fring wins points for its solid functionality, it also earns plenty for style. We like the scrolling buddy list with large lettering, the dialer, and the ability to punch one of two huge buttons after selecting a contact's name to place a chat or call. Fring has no capability to monitor your minutes, no hold button, and none of the other accouterments you might want for a regular phone dialer. However, most folks interested in inexpensive overseas bonding will be thrilled with this quick, dirty, and downright decent VoIP caller for iPhone.
