most phones should have an option not to store the data with the photo in the first place (not sure exactly what it would be on a HTC desire). There is EXIF viewer software as a addon to firefox etc or standalone ones that you can download to check this data. All digital cameras produce EXIF data – this contains not just GPS data but lots of things that are interesting for photographers like aperture, shutter speed, ISO. Unless you are really paranoid it doesn’t hurt to share this other data.
Blackberry allow you to turn geotagging on or off. What is annoying though is that there are times I actually want this data and when you do turn it on and check with software all position data is out by hundreds of metres. This seems to be because Canada records latitude/longitude differently to everyone else (some of the software I was using is Japanese, other ones are from Scandinavia)
Someone is getting their maths wrong and I don’t think its the Japanese or the Europeans.
Canada is big, so maybe a few hundred metres isn’t a big deal to them and blackberrys are not supposed to be used on board ship or anything life critical (the weather can be bad enough and leads to chaps with proper moustaches singing mournful songs about sunken vessels) but this kind of position error isn’t any good in smaller countries.
