I thought this was going to be something interesting like them encoding your private data into the dictionary set to obfuscate the communication. Apparently it's nothing at all.
Also worth noting iPhone sends a lot of information in the HTTP headers about your phone - like model number. Android does the same thing. Also simply plugging your phone in to USB (not accepting any on-screen dialogs) will save the IEMI and other device IDs into your system log. If you ever have a device stolen I suggest you run $(zgrep -i iphone /var/log/*.gz)
