CameraSync for iOS
These days, who wants to plug their iOS device into a computer to back up photos anymore? All of mine end up on Dropbox anyway, so why not cut out the middle man and upload the photos directly? This is where CameraSync comes in handy.
Once you’ve set it up with your Dropbox account (other options include Flickr, Amazon S3, Google Drive, SkyDrive, WebDAV, FTP, and Box.net), it will auto-sync all photos on your device with a folder in the cloud.
You can have it upload in the background based on your location, and it’s also possible to break down which things to sync: photos, screenshots, and/or videos. It remembers everything it uploads, so if you delete something from your cloud folder, CameraSync will stop syncing it in the future.
All in all, CameraSync is an awesome app. Get it on the iOS App Store for $3.
