Buried within the registry on the Tilt is a camera mode that some people here will no doubt be interested in.
“GPS Photo” is its name.

As the name implies, in this mode, the built-in GPS is activated, and EXIF tags with GPS data are embedded into the JPG files.

At the key:
HKEY_LOCAL_MACHINE\Software\HTC\Camera\P9

Change the value of “Enable” from 0 to 1

When you scroll through the different modes in the camera, the last one will be “GPS Photo” and it will begin initializing the GPS. You should be outside when you try this, or else the GPS will most likely fail to init.

Here’s what the EXIF data looks like.
