Thanks, briggs.

I knew I was being a bit intentionally newbish with the Juicy question - I had put it together myself already whilst reading various threads - it's just that everyone references it, but I didn't know where it came from... ha ha or whether Juicy was a user who programmed it, or a 'brand name', or what?
I'm a little scared to 'flash a new ROM'... is it like formatting my Windows XP hard drive and installing Linux?
And more importantly - are you telling me that my Touch Diamond DOES have GPS, but I just can't access it right now?? (And, of slightly lesser importance, FM radio?)
