Your friends on Sprint aren't the only ones that can flood your Google Voice number with MMS messages anymore -- now, even your T-Mobile pals can, too. Google's Nikhyl Singhal recently mentioned that Mountain View's been working on Voice MMS integration, so it's no surprise that another telcom's followed so quickly after The Now Network. Unfortunately, the process is nowhere near seamless: you don't actually get images, clips or whatever MMS file people send on your Voice account. Instead you get an SMS notification that a multimedia message was sent to your Gmail as an attachment. There's no word on whether the feature will follow for users on Verizon, AT&T and other carriers, but for now, you can always introduce friends and family to third-party messaging apps.
