The other day, we mentioned about running native, unmanaged code on Winodows Phone 7. The achievement was illuminating since it showed that advanced "rooting" can take place on WP7and that modifying system software was feasible. A milestone, indeed.
A minor, but important, advancement was just accomplished by the same developer, Chris Walsh, who just tweeted that he has managed to get "registry and file system access" on an HTC and Samsung device, noting that the LG was next. This is good news because it shows that this type of work is device independent--something we would assume to be the case, but as the Samsung/LG tethering tricks show, sometimes there are device level differences after all.
