Vonage has updated its Vonage Mobile calling app for the iPhone and iPod touch adding Bluetooth support and several other messaging related enhancements. Vonage Mobile allows iOS device users to place free voice-over-IP calls to other Vonage Mobile app users and make calls directly to landline phone numbers for low, per-minute rates with up to 3,000 minutes per month of free calls to phone numbers in the U.S., Canada and Puerto Rico for a limited time. Version 1.5 adds the ability to use any iOS-supported Bluetooth headset for making calls with the app and adds text messaging improvements allowing users to share address book contacts and include photos, locations and contacts in a single message. Users can also now open received locations directly in the Maps app and send website links to other Vonage Mobile users. The update also simplified the registration process and improves call quality, connectivity and performance. Vonage Mobile is available from the App Store as a free download. Calls to International and some domestic U.S. and Canadian numbers may require credit to be purchased via in-app purchase.
