Deciphering iOS Speak

If you have spent some additional time nosing around the About screen in your iDevice’s iOS or the home page in iTunes then you doubtless noticed some additional acronyms that may tickle your fancy.

  • square-blue.jpg The International Mobile Equipment Identity (IMEI) is a globally unique identifier for GSM iPhones or iPads.
  • square-blue.jpg The Integrated Circuit Card Identifier (ICCID) is a globally unique identifier for SIM cards.
  • square-blue.jpg The Electromagnetic Compatibility (EMC) number is defined in electrical engineering (Reference: http://is.gd/e8JE43) as the “ability of electronic equipment to be a ‘good electromagnetic neighbor’: It neither causes, nor is susceptible to, electromagnetic interference (within the limits of applicable standards).”
  • square-blue.jpg The Integrated Circuit Card ID (ICCID) is a yet another globally unique identifier associated with a GSM iDevice’s SIM card. What’s interesting is that you can run an ICCID through a mathematical formula in order to yield the subscriber’s IMSI (International Mobile Subscriber Identity) number.
  • square-blue.jpg The Unique Device ID (UDID) is a globally unique identifier associated with your iDevice that is used by iOS app developers to provision apps prior to their approval and availability at the Apple App Store.

As I mentioned in the earlier sidebar “Finding the Serial Number in iTunes,” you can toggle through your iDevice’s unique identifiers from within iTunes.

Okay, friends: Time for another experiment. Take your nearest iPhone, iPod touch, or iPad and turn it over. At this point you should feel proud of yourself inasmuch as you understand most of the information that is etched there.

However, the vast majority of iDevice users have no earthly idea what the collection of symbols (I affectionately refer to them as “hieroglyphics”) means. Take another look at Figure 4.3 that shows an iDevice rear case and then read the meaning of each symbol, which is explained in the following list (working from left to right).

  1. Approval seal of the US Federal Communications Commission (FCC). Note that the iPhone carries the FCC ID (grantee code) on the back case as well.
  2. Compliance seal with the Waste Electrical and Electronic Equipment (WEEE) directive. This signifies that the iDevice can be disposed of in an environmentally responsible way.
  3. Conformité Européene (CE) approval mark. This signifies that the device may be sold legally in the European Union (EU).
  4. Refers to the body that approved the device for CE certification. 0682 refers to Cetecom ICT Services in Germany.
  5. Alerts you of the iDevice’s status as a Class II wireless device, which means that the iDevice may attempt to operate on wireless frequency bands that some countries disallow.

Whew—that was a heavy slog through acronymville, wasn’t it? It’s time to lighten things up by covering how warranty repair orders work for iDevices. Next we’ll describe some aspects of an electrostatic discharge (ESD)-friendly workspace. After that I share some best practices, won through hard-earned experience, for organizing that workspace.
