I want to transfer photos off of my iPhone 4 without plugging it into my Mac. What's the best way to do this (the best option I see now is to email the photos to myself 5 at a time)?
If you have a Dropbox account, you can upload photos to that and it will automatically sync with any computers you have that are also running Dropbox.
I had this same problem when I was on the train with no cable of internet connection,
turn bluetooth on your iphone in your setting on the home screen of your iphone,
then turn bluetooth on on your mac,
you can do this by going system preferences > bluetooth i think
or to make it easier go to this page which tells you how to activate bluetooth on a mac
then pair the devices which you find out how to do it one this page
and away you go, share your pics
