Could this be the first peek of the 2010 iPhone 4G... the SIM car tray?! If not, could it be for the iTablet? Engadget says:

procured from Foxconn (the rumored Apple tablet manufacturer) and available for $14.05 starting October 23rd for the 4th generation iPhone / iTablet... whatever the mythical host device might ultimately be named.

And here we thought we'd have to wait until next year for rumors like this! Cue the case-maker leaks in 5... 4... 3..
