1.9 Will there be a version for iPhone/iPad, Android, Blackberry, or Windows Phone 7?
We are not planning to make a native "Application" for any of these platforms. Instead, we are working on an approach to support modern mobile devices in a completely platform independent way. We've made pretty good progress on this project recently, but we do not yet have a firm date when it will be available. Rest assured that we won't keep it a secret when it's ready!
In the meanwhile, the most portable way to run VCDS is to use a Netbook PC. These are small enough to fit in your glove box and cost less than a typical smart phone. Current ones usually come with Windows 7 Starter Edition, and VCDS works fine with this. Older ones normally came with XP-Home and VCDS works fine on that as well.
