If you haven’t found anything in the avalanche of iPhone Twitter apps that satisfies you, maybe this little feature will make you happy?

Twitter recently announced that they have added support to attach photos to your Twitter timeline using MMS. Now, all you need to do is snap a photo, send it to the Twitter number that corresponds to your country, and Voila; your photo appears on your Twitter timeline in a matter of seconds.

If you want to start sending photos via MMS, you will first need to setup and verify your phone number to communicate with Twitter. You can do so on the mobile settings page of your Twitter profile.

Personally, I don’t see much of a need for this, since I love Echofon, but if you still haven’t found an app that fancies you, this could very well be a viable alternative.

Let me now what you think about Twitter’s new MMS photo capabilities in the comments below.
