GV Mobile is not made by Google, but purports to allow access to Google Voice (formerly GrandCentral). No word on cost or when this app might be available yet (if ever), so do not get too excited!
GV Mobile would allows users of Google Voice to:
- dial numbers (domestic for free and international at a variable rate) via the iPhone’s address book or typing in on the keypad
- send SMS messages
- retrieve and delete recent call history
- playback and delete voicemails
- take calls from different phones other than your iPhone
- add, delete, enable, or disable the phones that Google Voice forwards calls to
