Giggs:
When I flashed the ROM I currently have on my Desire I got an email from Google congratulating me on buying a Nexus One. WTF I thought and when I checked the About Phone settings sure enough it said Nexus One.
When I looked at the thread I got the ROM from people had been complaining about the camera taking photos with a green tinge. Someone posted a fix and it changed my phone to a Desire. Apparently the problem was to do with the phone thinking it was a Nexus One.
Random.
Haha yeah it was shocking to see that my Desire had decided to think it was a Nexus One. Although I don't recall any green tinge in my photos :)
The problem appears to be a bug in an earlier build of the MCR ROM I'm running (which has since been fixed), so I just baked a newer mod, performed a full wipe and re-flashed the newer ROM. All is good again!! Except when I restored all my settings and apps via Titanium Backup, the problem came back (I presume the bug was lurking somewhere deep within a system file I had inadvertently backed up), so I wiped and re-flashed a second time, and manually re-added my apps.
Problem solved :)
