Dropbox (a free cloud storage service) has a free app (for iphone or android) that does this. One of it's features is "Camera Upload". You can set it to automatically save any pictures you take on your phone to your cloud storage and it will sync that photo to any other device you choose to access Dropbox from. This is all done seamlessly using your phones normal camera function.
I use this service and it is fantastic. My two home computers and my two different cell phones are all linked together on my Dropbox account and any photo I take on my phone is almost instantly available to any other device. It's also great for storing other files you might want to access anywhere. I have documents, videos, photos, music and even a few installable programs saved to my Dropbox.
Even if your phone is "confiscated" and they are savvy enough to delete any photo from your Dropbox, you can access your Dropbox from any other device and undelete it. You can also unlink that phone from Dropbox preventing them from accessing your Dropbox at all.

Very good! Bookmarked.
