Should your law firm create its own iPhone app?

With an estimated 30 million iPhone users and another 600,000 in line for the newest version, set to be released this week, some lawyers are launching their own iPhone apps to market their firms.

When international law firm Morrison and Foerster released an iPhone app that provides content from its website and blog, it got good reviews for its look and feel.

"It's nice. It's designed to catch your attention. It even includes a game on there," said Jeff Richardson, a New Orleans attorney who blogs at iPhoneJD.

But it also generated a debate over whether every law firm should come out with its own app.

"I don't see why not. If you're a small firm you want to think about the most [marketing] bang for your buck. If you're already creating content for your web page and your blog, you're really repurposing content in another package [by creating an app]," said Martha Sperry, an attorney in Boston who launched an iPhone app that aggregates content and provides links and a feed to promote her legal consulting business Advantage Advocates.
