What Is A Micro SIM And If The iPad Is Using It, Will iPhone 4G Get It Too?

In our previous article, we mentioned the micro SIM , and many of you asked all sorts of questions about it. Basically, to resume all the emails, i can break it down into 2 questions:

  1. What the hell is this Micro SIM?
  2. Micro SIM? Does the 4th gen iPhone will use this tiny SIM?

1. What the hell is this Micro SIM?

During the Apple keynote, uncle Steve said that the iPad will be unlocked and will use a micro SIM to get its 3G data. So basically, if the carrier of your choice support micro SIMs , you are free to use that carrier. But everybody ( including us ) had a brain block when Steve Jobs said “unlocked” and didn’t pay too much attention at the “micro SIM” part.

Micro SIMs or 3FF SIMs were developed by the European Telecommunications Standards Institute to fit into devices too small for a regular SIM. Where a regular SIM measures 15 millimeters x 25 mm, a 3FF SIM card measures 12mm x 15mm.

The SIM cards we use today, or the “regular SIM” is the 2FF and is a second generation SIM. In North American you will be able to find them at AT&T since they are supporting the iPad with data plans and in the near future T-Mobile. Probably in the long run, everybody will get on board.

2. Micro SIM? Does the 4th gen iPhone will use this tiny SIM?

There’s a strong chance the iPhone will get it too. Apple can use all the extra space but d0n’t get your hopes too high for an “unlocked” iPhone.
