MEDL Mobile (http://www.medlmobile.com), which specializes in mobile
application development, is making their photo and drawing chat app,
Doodle Chat, free for all iPhone and iTouch users. Doodle Chat allows
users to communicate by doodling messages back and forth, by sending
photos, drawing on photos, adding captions, and more.

“The new Apple 3.0 iPhone Operating System supports image-based MMS
chatting, but AT&T has delayed it here in the U.S.,” says MEDL Mobile
co-founder Dave Swartz. “So we decided to make Doodle Chat free to
fill the gap. Besides, it’s a whole lot better.”
