Google has released an update to its native Google Voice app for the iPhone adding support for multi-recipient texting and integration for Sprint iPhone users. The latest update now allows users to send text messages to multiple recipients via the Google Voice service along with autocompletion when entering contact names. For Sprint iPhone users who have integrated their Sprint service with Google Voice the app also now sends all calls through to the native iOS dialer allowing calls to be more quickly and easily completed. The update also adds a multi-line text entry field with character count and one-touch copy and paste on the dial pad screen. Google Voice is available from the App Store as a free download.
