Ive seen this a few times on two FR phones (both up to date 2007.2).
Yesterday, after using gps on the way to work tangogps locked up - some
10 minutes later when I pulled into the car park I picked the phone up
and it was *very* warm to touch.  I managed to exit tango (not always
possible - its not the most stable app after running 30mins or so!) and
checked the battery - ~38% when it was ~90% 45 minutes before.  10
minutes later in my office it was down to ~10% and still hot so I
rebooted and recharged.  This has happened maybe 5 times to me now.  The
other phone user had a flattened battery after a few hours - dont know
the exact details but gps wasnt involved.  The phone was hot enough that
I was worried about putting it in my pocket in case the li-lion battery
went up in smoke.  I expected it to cool down once I had exited tango,
but it didnt until reboot.  I was more worried about damage than finding
the root cause - next time!
