To see what all is available to you, go to "Settings", swipe over to "Applications", select "photos+camera", and scroll down to "Auto Upload". There you'll see Skydrive, which is built into the phone, or you can click on "Apps" then choose "Find Apps". I don't see any apps that auto-upload to multiple clouds, but there's no reason you couldn't install more than one of those apps and upload to whatever service you want. Looks like there's decent solutions for DropBox, AT&T Locker, ImageShack, Shutterfly, Picasa, and maybe a few others. "Viewr for Flickr" says it'll have auto-upload in the next update. Choose your service(s) then choose your app.
