I rooted my Desire last night using the Unrevoked method. Everything worked perfectly well and I now have superuser permissions. However during the install, when I was supposed to do a backup within the Clockwork recovery........I was too busy reading my laptop and my phone automatically rebooted. My question is basically, do I need to do a backup in CLockwork recovery before I begin attempting to flash a custom ROM? I have installed Titanium Backup and will do a backup using that. My most humble apologies if I sound like a complete idiot!
