Well, it's about a month and a half behind its Android counterpart
(and what feels like decades behind the web interface), but the iOS Google Voice
app finally (finally!
) has support for multi-recipient texting. Version 184.108.40.2062 adds few other nice tweaks, including one touch copy and paste on the dialpad and a larger text entry field with a character count but, obviously, the mass texting capabilities here steal the show. So hit up the App Store to update now and start spamming all your friends.
