Apple’s iPhone 5 was just announced today, and you can pre-order it on Friday. Apple used micro-SIM cards in its iPhone 4 and iPhone 4S products, but this time it switched things up a bit and is now using a brand new Nano-SIM card. In other words, you’ll need a new SIM card if you upgrade to the iPhone 5 because it isn’t compatible with the older micro-SIM technology. This doesn’t come as a surprise, however, since several leaks suggested Apple was moving toward the new standard, which was recently formalized by ETSI and is 40% smaller than a micro-SIM card.
Apple’s spec site, which confirmed that fact, also confirms that we’ll see the iPhone 5 launch on AT&T, Sprint and Verizon Wireless in the United States.
