Riverturn has entered into the Google Voice for iPhone arena with it's latest offering VoiceCentral Black Swan. Google Voice and iPhone have a long history together and it has not been pretty, until now that is.
Black Swan is an application you can get outside of the App Store and you do not need to have a jailbroken device. It is not a web app like the official Google solution but rather a feature rich "weblication" that enables you to view and manage your Google Voice data just like you would with a native iPhone application. As you can see by the following features, no stone as been left unturned with this app:
Simply visit the Black Swan web site directly from your iPhone to download. You will have a choice to select between two versions - free (ad-supported) or premium. The premium version will run you $6.00 a year and for that you will also get zero ads, the ability to import contact photos, favorites, ability to search your inbox, and a do not disturb option.
This is hands down the best current solution for those of you who use Google Voice on your iPhones. Be sure to check out the demo of Black Swan in action and let us know how it works for you in the comments below!
