Google has released a Google Voice app for iPhone. This comes after apple eased its restrictions on third party apps earlier this year and we started to see third party apps for Google Voice pop up in the App Store.
The official Google Voice app is availabel as a free download and it supports key Google Voice features including the ability to make inexpensive phone calls to international numbers, send free text messages to US numbers, and receive automated (and pretty bad) transcriptions of voicemail messages.
The new app also supports push notifications, so you get a message letting you know when a new text or voice message is waiting for you.
Google Voice supports iOS 3.1 and up, but it does not support the iPod touch or iPad. The software is iPhone-only, at least for now. It’s also US only, since Google Voice is only available in the US.
