Using Your New WP7 Phone As A Mass Storage Device
"MobileTechWorld has discovered that Windows Phone 7 can be used as a mass storage device. According to the site, there's no "hacking" involved, as the feature is native to Windows Phone 7 but turned off by default. Users simply need to alter the Windows registry on the PC to re-activate USB drive mode support."
I'm certainly not suggesting that you run out and do this, as there are potential issues with taking advantage of this option, but should you desire to use your new Windows Phone 7 device for mass storage, then Tom's Guide has reported that MobileTechWorld has the exact steps to follow to make it happen. Those brave enough to try this report success, although there are limitations (such as file recognition issues) that may curtail the overall usefulness of the hack. Click through to find out more.
