Find someone else who has one, however you do it, and try Beam. Just hold the two devices back to back and tap the screen of the one you want to share from. Hey presto, the photo, app, maps place page, game, contact, anything is transferred across. It's not totally instant but it is very cool.
Don't forget your cloud storage, sign up for Dropbox here and get 2.5gb instead of the usual 2gb
