Having had my HTC Desire S made S-Off by Androf ( Root internet cafe on Edgware Rd London ) I noticed that there are a few methods to root the DS.
Most of which are quite complicated but alas I managed to find a simple method.
The Gingerbreak 1.20 APK manages to root any S-Off DS quickly and easily, simply download the app directly to the phone or download and transfer to the phone. Once that has been done simply install the APK file onto the phone, once that is done simply run the app and follow the instructions and then your phone should say something along the lines of there was a mistake and try a manual reboot to check if Superuser is installed.
For a few people such as myself you may notice that once you run the Gingerbreak APK the phone reboots itself and doesn't work, if this happens to you then simply format your SD card and remount it and try again and "voila" you should have superuser installed and root access on the DS.
Hope this helps anyone that may have encountered the same problems as me.
