I know, you're all waiting eagerly for the release of the iPhone, Apple Inc.'s (NASDAQ: AAPL) long-awaited mega phone. Or maybe you've decided you're an upscale type and are willing to wait even longer for the U.S. release of LG's Prada phone (currently sold in Europe for about $800 USD, and to be offered on the Verizon (NYSE: VZ) network), expected in "late summer" 2007. Didn't you realize there's a third option for the status-hungry, dripping-with-money types?

For only $300,000, or thereabouts, you could be dripping in mobile phone-ness with the Vertu "Signature Cobra," pictured here. Only eight of the phones -- encrusted with 439 rubies and wicked emerald cobra eyes -- will be produced, but you'll have to special-order. Vertu is known for its excessively fashionable technology; its phone service features a "concierge" button which connects you to personal assistance for travel, restaurants, and events.

While the concierge sure beats the Apple iPhone's ability to Google "Starbucks" and then call and order 4,000 lattes (haha Steve! you're such a funny one), I think I'd rather have yummy technology than eye-popping jewelry. And wouldn't it suck if you left your phone in a cab?
