Google Voice notifications on your Computer - and iPhone

Computer

You can get notifications for Voicemail and Text (SMS) Messages on your computer when they are received on your Google Voice account!
To achieve this we will use Growl for Windows, FireFox, FireFox Growl/GNTP Add-On, and FireFox Greasemonkey Add-On.

Downloads:
Growl for Windows
FireFox
Greasemonkey Add-On
Growl/GNTP Add-On

Once Growl is installed I recommend running it at login (Option in Growl)

You will need to install FireFox (if you dont have it already) before install the Add-Ons.

Once you have those installed you will need to go here and install the Google Voice Greasemonkey Script by clicking Install near the upper right corner.

Now that you have done that go to the Google Voice webpage - here

It should say Google Voice is registered to receive Growl Notifications.

You will now receive notifications of new Google Voice alerts! The only problem being here is that I believe you need to keep FireFox OPEN with your Google Voice account open in a Window or Tab. But either way this is very useful! I use it myself.

iPhone

You will need to get an App from the AppStore called Prowl: Growl for iPhone. It does cost but only $2.99. If you want to get it by other methods thats fine but I will not give any links to other methods

Open Prowl and register a new account. Once registered visit this address on your computer https://prowl.weks.net/ and log in with the account you created. Press the button to create an API key. Now copy that key. Or save it somehow

You will need to open Growl on your computer and go to the Network tab and click "Forward notifications to other computers"
Now click the Plus button (green) and choose iPhone and choose a name for your device.
Now paste in the API key you got from Prowl.

Now thats it! You get Google Voice notifications on your Computer and your iPhone! - Only thing I dislike is the need to keep Google Voice and FireFox open.. But for most of the day that isnt a problem for me and probably for more people it wont be a problem for some of the day.

Enjoy!
