Mobile device makers Apple and Research in Motion are gearing up with new software updates to make their smartphones more driver-friendly.

Apple announced last week that its new OS 4, which will be released this summer, will allow iPhone models to run multiple applications while RIM forged a deal with QNX Software Systems.

According to the The New York Times’ blog “Wheels,” Apple’s update includes a feature called “iPod Out,” which will allow developers to integrate iPhone apps with car stereo and navigation systems. This means, drivers can simultaneously listen to music while using their iPhone’s GPS system.

For RIM, maker of the popular Blackberry phones, the deal with QNX may lead to various innovations. QNX develops software for the infotainment and telematics systems of more than 200 different car models, and RIM will surely benefit from QNX’s deep automotive knowledge. A Blackberry phone that doubles as a remote starter or remote lock is not a far-fetched idea with this new partnership.

While the two companies have loyal customer bases eager to try their new offerings, it remains to be seen whether car manufacturers will buy the idea.
