HTC on Tuesday released yet another Android-based smartphone, dubbed Tattoo, which promises a higher level of customization.

“The HTC Tattoo ensures that you can create the most engaging and appropriate mobile experience through simple yet powerful personalization,” the company said in a statement.

HTC’s Tattoo is the second phone, after the Hero, to use Sense, the company’s proprietary user interface. Sense allows people to open as many as seven applications at the same time and run customized applications.

This is the fourth phone produced by the Taiwanese phone maker based on  Google's open-source Android operating system. The third model, Hero, a touch-screen smart phone, was launched last week by Sprint Nextel, a little less than a year after the release of the first ever Android-based smart phone,  the G1.

Google is the latest agitator on the fast-moving smartphone OS market that counts players such as Apple, with over 30 million devices sold, and Research In Motion, with 28.5 million BlackBerry subscribers worldwide.

The 3G Tattoo smart phone sports a 2.8-inch touchscreen and comes with a 3.2 mega pixel camera, 3.5mm stereo headset jack, and an expandable micro SD memory.

The device will start selling on the European market early in October and will launch in other markets the following month, the company said.
