Google Voice in your iPhone

"Apple may have blocked the Google Voice internet telephony app from its App Store, but Google has executed a nifty end-run around the blockade by releasing Google Voice as a web page that is accessible by any HTML5 web browser. Simply direct your iPhone or Palm Pre to google.com/voice to make calls from your Google Voice account (Android and Blackberry owners can just keep using their native Google Voice apps)" (2010, Wired.com)

Actually I like this approach, because you don't have to download any software to your iPhone. Just point your safari internet browser URL address to http://www.google.com/voice, login using your account ID and password, you're ready to call anyone, and not wasting your mobile air minutes. While in the same screen, click the (+) sign to book mark "Add to Home Screen" so that it will look like a native apps.
