After biting the bullet and rooting my t-mobile HTC Desire using unrevoked3 I now have super user access. I've installed Titanium Backup and Rom Manager and downloaded a couple of ROMs to try out. I tried DeFrost 2.7 from Droid Den and CyanogenMod 6.0.0 downloaded direct through ROM manager. I backed up and tried to get the new ROMs running. Both times the phone went through the backup and boot process with everything looking fine but when it started up it wouldn't fully boot. With the CyanogenMod I just got the CyanogenMod blue circle/arrow animation cycling over and over and with DeFrost never got past the pink circle, even after leaving it for an hour. I can take out the battery and restore through nandroid no problem but obviously one of the main reasons to root is to try new roms. I was hoping someone can see what I'm missing here
