Hello
Latest correction in http://code.google.com/p/jsjpegmeta/issues/detail?id=3#makechanges did not fix the problem.
When uploading a photo from camera roll on IOS 6 exif data (GPS coordinates) is not retrieved and we had to default to the gps position of the device to find out the position.
We use the page https://activ-ha.com/activer if you want to have a look
Thanks
