Apple Inc.'s iPhone 4S, which was unveiled on Oct. 4, will be hitting the stores on Oct. 14. The smartphone from Apple is going to face a tight competition with Motorola Droid Bionic.

As it turned out, iPhone 4S featured some important upgrades that were rumored to be a part of the imaginary iPhone 5, like the 1GHz dual-core ARM Cortex-A9 processor, PowerVR SGX543MP2 GPU, an Apple A5 chipset and a 8-megapixel camera. It also has a 3.5-inch TFT Retina multi-touch display and is loaded with the latest Apple operating system iOS 5.

iPhone 4S also comes with alternating antennae for better call reception, CDMA and GSM support, a personal assistant called Siri, iCloud and Bluetooth 4.0 wireless technology. However, missing were prominent specs like edge-to-edge design, a larger display, 4G LTE and Near Field Communication (NFC) technology.

On the other hand, Droid Bionic hit the shelves in September, more than eight months after the device was unveiled at the Consumer Electronics Show in Las Vegas, Nev. in January.

The 4G LTE, dual-chip Droid Bionic had been delayed for months as Motorola gave it numerous changes, allowing it to compete with the high-end phones of the industry.

Specs on the Droid Bionic are impressive. The phone comes with a 4.3-inch HD screen featuring the Corning Gorilla scratch-free screen, two cameras: front-facing for video chat and 8-mega-pixel back camera, Adobe Flash preloaded, 32 GB of memory and a slim frame. It has a dual-core 1 GHz processor and 1 GB of RAM and runs on the Android 2.3.4 Gingerbread operating system.

The Motorola smartphone comes with a cloud-friendly app Zumocast, which lets users bring videos, music, pictures and documents stored on their computers to their handset via remote access.
