The latest update to Google Voice for the iPhone centers on the addition of multiple number entries for sending a text message to and a further update that allows it to support Google Voice on the native dialer if being used on the Sprint iPhone. Such updates were long requested and should make it easier to use Google Voice in place of the native functionality along with a multi line text entry field. The update is now available in the App Store.
It should be noted that the latest update is causing some users issues as many are reporting that the phone’s actual mobile number will display on the caller id of the recipient on outgoing calls instead of the Google Voice number even if the settings are configured to display the Google Voice number only.
