Dropbox Photo Sync
"It’s still beta, but the Dropbox camera sync is very convenient. Whenever I physically connect my iPhone, all of the new photos and videos are downloaded into Dropbox. While it’s not wireless syncing it is a big step forward. Get the forum build 1.3.6 to enable the feature.”
Disconnect your phone if it’s connected, reconnect, and you get a dialog asking whether you want to import photos automatically. Works wonderfully. I just wish they wouldn’t put all photos in one folder though.
