As we wrote a month ago, Google Voice finally arrived for the iPhone after Apple waited 16 months to approve the application. And as expected, the app was a hit with Google Voice and iPhone users. Unfortunately, at the time of launch, Google Voice for the iPhone didn't support the iPod Touch or the iPad. So today, Google is announcing a new version of Google Voice that will work on both iOS devices. The new version of the app essentially allows you to use all the features of its iPhone cousin, including the ability to read your voicemail and send and receive text messages. Of course, you cannot make cell calls from the iPad and the iPod Touch. But you can use Google Voice's Click2Call feature to initiate Google Voice calls with one of your phones.
