I use GPX Master for my iphone, I get the GPX file by connecting to the PC open itunes, open the device, select apps tab, scroll down and find file sharing, ( the apps below can transfer...) select GPX Master (in my case), get the list of GPX tracks, select 1 or more, scroll to bottom of list, select save to, browse to your folder on your PC and click select folder then find your selected tracks in the folder ready to use.
The second time you use it it will appear to be in the correct folder but itunes (or is it windows) is too stupid to just allow you to hit select folder, you will need to back up one then select the folder to make it active (your folder name next to where it says folder at the bottom of the box).
This bit I have mastered, where my tagging turns to s%#} is when I sync with Geo Setter, and the tracks come out miles off! I have set the PC time to the phone time then got the camera time correction box showing the correct camera time to the second, click sync and the pics are put on the map in completely the wrong place!?!?
Then when I try to adjust timings it gives me a you have exceeded the 2000 credits limit, use a commercial tool?
Im going traveling for 5 months, I intend to geotag my images. I just wish the GP-E2 wasn't so big bulky and ridiculous. otherwise I would buy one. I think I am going to either buy a some kind of GPS watch or use my phone, but battery life apparently isn't great when using GPS via iPhone. Also a pain that apps such as geotag photo only sends the gpx file via dropbox or email, when your in the middle of nowhere with no internet how are you supposed to get the GPX to your laptop?
