Google Voice for Android now supports sending text messages to multiple recipients. Being able to have a single, archived repository of texts is great, but it was always somewhat bewildering that while you could send a mass SMS from the website you were stuck sending out individual missives on the app. Today's update, version 0.4.2.38, finally gives Voice the power to spam your contacts -- a pretty basic feature that even the lowliest of feature phones enjoys. So what are you waiting for, head over to the Market to get the update now. How else are you going to let all 300 of your closest acquaintances know the next time you're DJing during happy hour?
