As a tribute to its past popularity, Motorola has brought the name Razr back to the phone, with the unveiling of the new Droid Razr.

Motorola Mobility President Sanjay Jha declared the 7.1mm mobile device the world's thinnest smartphone.

The Motorola Razr is 7.1 mm (0.28 in) thick and weighs 127 grams (4.5 ounces). It has a 4.3in Super AMOLED display with a qHD resolution of 540x960, is powered by a 1.2GHz dual-core processor, has 1GB of RAM and 16GB of internal memory with a microSD card slot for extra storage. The new Razr also has an 8-megapixel rear-facing camera with full HD 1080p video recording and a 2-megapixel front-facing camera that will record 720p HD video.

The new Motorola Razr will run the 2.3 Gingerbread version of Google's Android platform and comes with the latest version of the company's Motoblur software.

The Razr also has MotoCast, a syncing system that Jha calls the phone's most important feature. You can stream content from your computer straight to your pocket (or purse) so your personal content is always within reach, says the press release. And, because you don’t have to upload to a third-party site, you’re saving time while gaining peace of mind. That’s right — your files stay safe because they stay with you.

Internally, Smart Actions allow it to save up to 30 percent of the battery life by doing things like turning off Bluetooth and GPS when the user gets to work, and can make his life easier by automatically switching from ring to vibrate when going to church or some high-powered conference.

Motorola's Droid Razr will be available for pre-order from Oct. 27 and will be available in Verizon Wireless stores in early November. Verizon will sell it for $300 with a two-year contract. The Droid Razr will use Verizon's new LTE high-speed wireless data network.
