Sandwiched between two layers of Gorilla Glass, your iPhone’s innards are a thickly packed tissue of silicon, precious metals, plastic and Li-Ion power cells. Space is at such a premium inside an iPhone that literally every milimeter counts, which is why Apple is always at the forefront of technologies that will make a critical component just a little smaller, a little thinner.
Foremost among these is the venerable SIM card. Apple first managed to reduce the physical footprint of the SIM card with the iPhone 4 with the micro SIM, and now they want to do it again with the nanoSIM.
The only problem? The rest of the industry doesn’t like the nano SIM, and now Nokia is speaking out against it.
