I rooted using SuperOneClick. When I ran Ti Backup the first time and had it check busy box, it upgraded to 1.18, but I went back to 1.17 using busybox installer. I just un rooted and re-rooted (had to stop in at the dealer to check the GPS...) and now have 1.17 again.
I've tried ES file explorer and Astro, and the mount system rw application. When I go to the root, and look in the data directory, it is empty. ls in adb shell returns opendir failed, permission denied.
