Google Voice for Android received a new feature called “Inbox synchronization,” which notify Android-powered device of new text messages or voicemails within seconds (previously 15 minutes) of receiving new messages in Google Voice inbox. To activate Inbox synchronization, open Google Voice settings on your phone and touch Refresh and notification. Once you selected Synchronize Inbox option, you’ll start receiving faster notifications. Plus, Google Voice will automatically disable SMS forwarding to your mobile phone, so you won’t receive duplicate notifications. Finally, its now much faster to interact with contacts from the Google Voice app. Now you can click on any contact photo and get the option to quickly respond to voicemail by email or IM. You’ll need a valid Google Voice account to use the app, and at this time, Google Voice is available in the US only.
