Celio is investigating a version of its Redfly mobile companions for the iPhone, a company representative has told Electronista at an event ahead of CTIA. While no definitive support has been planned, the device maker says it has already been experimenting with drivers that would let a connected iPhone use a Redfly's larger screen and keyboard. It's not certain whether this would include every feature or whether it would connect through Bluetooth, USB, or both.

The key obstacle is how much control Apple allows in iPhone OS 3.0, the official says. Apple describes its upcoming firmware as allowing direct hardware acess and letting developers write their own protocols to access components. Most developers have yet to fully explore the new iPhone SDK and thus learn what they can expose in official apps for the iPhone. Redfly's spokesperson hints that jailbreaking iPhones to force full hardware access may have been involved in testing in the past, but also that it's very unlikely to ever be used for a finished product.

News of exploring Redfly support comes two months after the company first demonstrated Google's rival Android working with Redfly devices and just as the company has launched a beta remote viewer for Windows PCs.
