To get your atria 4g to have the same installer as windows download the Motorola link here:

http://www.motorola.com/Consumers/US-EN/Consumer-Product-and-Services/Mobile+Phone+Accessories/Software/Motorola-Media-Link-Mac-Version-US-EN

Once you have this installed you will have a application in the applications folder, plug your phone into the usb drive and run the Motorola App

This will allow you to sink from your computer to you mac.

If you click on the MOT drive on your desktop you will get access to the file system. For example you want to add or delete files you would have something like this

This would be in Android/Data

Best of all this fixes all the problems with testing AIR for Android appps on the phone!
