We’ve told you about Line2 before. The VOIP (Voice Over Internet Protocol) service, which launched July 28th last year, turns your iPad (or iPhone) into a second phone line for just $9.99 a month.

We haven’t heard much from the company since then, but this week they’re out with a fairly big announcement. It seems they’ve added an MMS (Multimedia Messaging) feature to the service…

From Line2’s blog post:

“We have heard your feedback and are happy to announce that Line2 now offers picture and location sharing on iOS! Video is coming soon!

If you send an MMS from a Line2 number to another Line2 number, the attachment will appear directly within the application.

If you send an MMS from a Line2 number to a number outside of our network, your outgoing MMS will be sent as a link connecting the viewer to your image hosted outside of the application.”

The service’s big downfall is that you can’t receive an MMS from a line outside of Line2’s network. They attribute it to “anti-competitive behavior” from the cell phone carriers, but no matter how you slice it, it’s still a major inconvenience.

Regardless, for just $10 a month, this is still a decent solution for turning your iPad into a 2nd phone line. All you need is iOS 5 or higher to take advantage of the new MMS feature. You can download Line2 from the App Store for free.
