The iPhone 5s features the same 4-inch (diagonal) Retina display with 1136 x 640 resolution and 326 ppi (pixels per inch) as the iPhone 5c and iPhone 5. The iPhone 5s display has an aspect ratio of 16:9.
Walmart has announced that it will offer the 16GB iPhone 5c for $79 and the 16GB iPhone 5s for $189. $20 is a pretty substantial discount for a new Apple product, and the $79 price point makes the iPhone 5c actually sound affordable. Both deals require that you sign a new two year contract with either AT&T, Verizon Wireless or Sprint, and are in-store only. You may want to call ahead to verify prices and availability before heading down to your local Walmart, in case they sell out.
Apple will begin accepting pre-orders for the iPhone 5c on September 13, 2013. The plastic iPhone will be available in lime green, white, yellow, red and blue starting at $99 for the 16GB model, and $199 for the 32GB model. Apple is not accepting pre-orders for the iPhone 5s. It will be available in space gray, silver and gold at your local Apple store starting at 8:00 a.m. on September 20.
While Apple has provided few details regarding how they accomplish fingerprint authentication without doing so -- likely due to the fact that the technology is proprietary and protected -- Apple has stated clearly that they will not be storing anyone's fingerprints.
According to the official Touch ID video:
All fingerprint data is encrypted, and stored in the secure enclave in our new A7 chip. Here it is locked away from everything else, accessible only by the Touch ID sensor.
Yes, but only from Apple (for now).
Initially, you'll be able to use the iPhone 5s fingerprint sensor to authorize purchases on the iTunes store, through iBooks and the App Store. In other words, in all the places you previously had to enter your iTunes password.
It should be safe to assume that Apple will eventually allow Passbook purchases to be authorized via the fingerprint sensor as well, but no official word on that yet.
If you're not eligible for an upgrade with your wireless carrier, you'll have to pay full-retail pricing for the iPhone 5s in order to own one.
