   On computing devices that support booting from a second OS, you can   
   gain "dd" access from the second OS. On my MacG4, I booted the Ubuntu PPC   
   DVD, and used Ubuntu "dd" to transfer out the disk (which would be at-rest).   
   I used a command line FTP session, and you can mix shell commands into   
   the ftp commands -- dd can be piped into a (binary) "put". And on the computer   
   I did that on, the GbE at 112MB/sec, that's the fastest interface it has got.   
      
   But something like a phone, there are fewer opportunities for tricks like that.   
   Rooting the phone, if you can manage it, is as close as you're getting   
   to a good time.   
      
   On at least one phone, the NAND is hidden underneath something, and   
   you can't cable up and read-out the NAND chip with external equipment.   
   For some of the devices, it's pretty well secured. You would not expect   
   a simple trick to work in such a case.
