In October 2011, Apple released the iPhone 4S for AT&T, Verizon,
and Sprint (newest addition to iPhone carriers). Featuring glass front
and back, a front and rear camera, and retina display, the iPhone 4S
looks identical to the iPhone 4. The iPhone 4S is externally identified
by the model number A1387.
Inside it now runs the A5 Processor just like the iPad 2. The rear
camera now sports an 8MP camera with LED flash and shoots full 1:1 1080p
video at 30 FPS while the front camera retains the VGA quality photos
and 30 FPS of its predecessor. The iPhone 4S also comes with an
integrated voice-controlled system named Siri. Siri can do many things
ranging from setting up reminders to doing web searches.
