Vonage, a digital phone services provider, has put out a brief press release stating that Apple has approved its iPhone app. The app is not yet available in the App Store and Vonage notes that it "is currently conducting a beta test and general availability will be announced at a later date."
It was revealed just last week that Vonage had submitted an iPhone app to the App Store for approval. The Vonage app will join the Skype app in offering VoIP connectivity to iPhone users and will likely share its Wi-Fi-only restriction. This restriction is required by an agreement with AT&T to not allow customers to use AT&T's network to initiate or terminate VoIP sessions, which was divulged recently in Apple's response to an FCC inquiry surrounding its purported rejection of the Google Voice app.
