The lack of MMS support causes much gnashing of teeth for those of us who use Google Voice extensively. Now, Google has started the process of addressing this shortcoming...for Sprint Android users.
Any MMS message sent by a Sprint user can be received to a Google Voice inbox, or email inbox. No doubt this is a limited development, but Google's promise to expand this feature to other carriers and services make it something to keep an eye on. [Google via PhoneScoop]
