You can get in there with the Android debugger but that's more than
little complicated and it doesn't let you restore.  You may be able to
do it via a custom recovery, but if you can do that then you already
have a mechanism for doing a complete dump and restore on the device
itself.

But the OS itself isn't the important thing to back up; you can reinstall that. What you want to back up is the data - contacts, calendar, and so forth. (Other files like music, ebooks, etc. are trivial.) Even if you couldn't restore those files directly, if you had them you could get the data out and then use some sort of script to stuff it back into the cloud applications like Gmail.

I don't know, however, whether you can get to those files. On the one occasion it mattered to me (when I moved to a new phone) it all just came down from the cloud so I didn't need to try anything else.

Apps that are no longer available (or where you prefer an older version) are another thing that would be nice to be able to back up. If you had the .apk files it would be easy but Android doesn't normally keep those around.

I didn't know that iOS now allowed USB access to some data. Have they opened up music at all or do you still have to sync it using iTunes?
