iPhone 4 Specs and Definition

The iPhone 4

Thanks to a leak of a pre-release version of the iPhone 4, and Apple's subsequent confirmation of the device, this model of the iPhone was revealed to the public before Apple officially announced it.

The iPhone 4 is visibly different from its predecessors, in that it's got a more square shape (gone are the iPhone 3GS' tapered sides), a microSIM slot on its side, and circular volume buttons on the left.

iPhone 4 Features

In addition to the standard features of an iPhone (cellular data connection and WiFi, iPod, multitouch screen, App Store support, GPS, etc.), the iPhone 4 sports:

  • Apple A4 processor (the same chip used in the iPad)
  • 720p (high-def) video recording at 30 frames/second, with LED flash; iMovie app for iPhone for on-camera video editing
  • a 3.5-inch, 960 x 640 display, with greater pixel density in the screen, leading to higher-quality images (326 pixels/inch), via Apple's Retina Display technology
  • 2 cameras - front- and back-facing, with LED camera flash for back camera
  • 5 megapixel camera
  • FaceTime video calls (only works on WiFi for now, iPhone 4 calling to iPhone 4 only)
  • 512MB of RAM
  • Gyroscope (combined with accelerometer to offer 6-axes for better gaming)
  • Existing apps take advantage of new screen resolution, but will look best with tweaking by developers
  • standard set of iPhone sensors
  • 24% thinner than iPhone 3GS
  • new body design, featuring glass front and back and steel sides. The seam near the bottom of the phone accommodates a larger antenna, which Apple says will result in fewer dropper calls.
