Defy with Froyo and broken geotags
Defy is a great phone, but after updating to Froyo GPS position in JPGs is gone... but it is not. Instead, geotags are broken. In fact, GPSLatitudeRef is invalid. For the North hemisphere it shows 'W', but should be 'N'.
So, I don't want to make any ROM-modifications in my phone, so I wrote a small application (for PC). It scans JPG files looking for the broken tag and fixes all invalid GPSLatitudeRef.
As for now, it seems that it works. It replaces only one byte in a JPG file, so the GPS position is again visible (e.g. in Picasa). So, before I make this app public, I want to make some more tests. Especially, I'm looking for broken photos made on the south hemishpere!
Moreover, I think that I'll make a program like this for Android, so the photos may be corrected instantly in the phone. Good idea?
