You can change it with adb. There are a couple of videos on this but I personally am having problems with it. adb recognizes the phone but won't do a remount in order to change the protected files. Per some other threads, I've ensured the phone is rooted and has busybox (running di11i v6 ROM), but still no go. I'm going to try more later (never enough time...).
Anyone have any ideas???
