iPhone?

[eluser]Bloom Apps[/eluser]
Hi,

We are days away from launching a private beta of a new web app called Bloom, which we built with CodeIgniter (very happy about that decision!).

One thing we're considering is an iPhone-friendly UI for the app. I was wondering what people's solutions are for offering an iPhone interface? Is there a tool out there within CI or are people just checking for the iPhone in the controller and loading a different view?

By the way, we're all "sold out" of July 31 beta invites. But we'll be sending out more invites in the coming weeks, so come by and sign up!

Thanks!
Chris
