I took my 3gs to Paris last year. I had data roaming turned off (didn't need it and didn't want to pay for international data). Anyway, after updating to iOS4, I noticed that my Paris photos place me in the ocean off the coast of Ghana. I tried to use Picasa to update the photos location to Paris. That seemed to work for Picasa, then I synced my phone and notice that the pictures are still off the coast of Ghana. How can I change the location of these photos? Using a PC not a Mac.
