While Apple Inc. is tight-lipped towards its iPhone 5 release date, the smartphone is expected to face a good deal of competition from Android devices, particularly from the Motorola Droid Bionic, which would be available at Verizon from Thursday.

Motorola Droid Bionic is the first Verizon Wireless smartphone to combine 4G LTE with the power of dual-core 1 GHz processors, 1 GB of RAM and a stunning 4.3-inch qHD display – all in a sleek form factor that makes it the thinnest 4G LTE smartphone from Verizon Wireless.

Droid Bionic will finally be available starting Sept. 8 and will be powered by Android 2.3.4 Gingerbread OS. It will come with several enhancements, including expanded features, functionality and an improved form factor.

Motorola's smartphone introduces ZumoCast, an application that lets customers bring their digital world of videos, music, pictures and documents stored on their computers to their handset via remote access.

With its revolutionary Webtop application, the phone can beam a full-featured Firefox Web browser 4.0, email or documents to a TV or monitor, like the separately purchased Lapdock with a 11.6-inch screen, keyboard and integrated trackpad.

Droid Bionic also comes with additional accessories such as the HD Station, which let users turn the phone into an entertainment center or home office, HDMI cable for viewing pictures, video, and content on any HDTV or monitor, and it lets users share 4G LTE signal with up to five Wi-Fi-enabled devices when they activate the Verizon Wireless Mobile Hotspot.

Apple is rumored to increase the screen size of iPhone 5 to compete with Android smartphones, probably going for a 4-inch screen, compared to the current iPhone 4 screen of 3.5-inch.

Deutsche Telekom AG (DTE) is now taking customer reservations for the next-generation of Apple Inc.'s iPhone 5 starting Sept. 5, as new evidence supports rumors that the iPhone 5, expected to be revealed in October.

Meanwhile, the next iteration of the iPhone is expected to boast of significant hardware and software upgrades, along with an 8-megapixel dual-LED flash camera and A5 dual-core processor found in the iPad 2 to give stiff competition to other dual-core smartphones found in the market today.

Apple may boost the speed of its A5 chip in the range of 1.2 or 1.5 GHz with 1GB RAM. The iPhone 5 would feature iCloud that will store photos, apps, calendars and documents instead of the phone's memory storage.

Apple is expected to release the iPhone 5 as a World Phone - both GSM and CDMA compatible. Another rumor suggested that the iPhone 5 will feature a SIM card slot for other countries except the U.S, allowing users to insert any SIM card when traveling abroad.
