Google is getting ready to launch the official Google Voice application for both Android and BlackBerry platforms. The application lets you make calls and send texts through your Google Voice number and integrates with the service’s excellent visual voicemail and voice transcription service.
“Today, we’re happy to announce Google Voice for mobile which brings voicemail transcriptions, the ability to call and text with your Voice number, and cheap international dialing to your mobile phone. David and I were inspired to build this app when we went skiing for a weekend in Tahoe. Like all good Google Mobile team members, we each had three or four phones with us. Of course, carrying three phones while skiing is pretty tough, so we both decided to take a different phone to the slopes each day to see which one worked best as a ‘winter sport device’.”
