Any time I discover another one of the secret codes that surround us, I’m happy. Along those lines, Cult of Mac had a neat little article titled Understand Your iPhone’s Serial Number that was right up my alley:

Serial numbers are presented in the form AABCCDDDEEF, and this is what those letters represent:

  • AA = Factory and machine ID

  • B = Year manufactured (this is simplified to the final digit, which means 0 = 2010; 1 = 2011; etc.)

  • CC = Week of production

  • DDD = Unique identifier (not the same thing as the Unique Device Identifier, or UDID)

  • EE = Model and color of device

  • F = Storage capacity of the device (S = 16GB; T = 32GB)

I love knowing stuff like that!
