As was expected, AT&T's femtocell service has arrived -- or at least the AT&T product website has gone live. The website, which AT&T says was designed with a single trial market in mind, gives users a detailed explanation of how specifically the device works. Most carriers get in the way of these devices really offering consumers value, for instance Verizon's service bizarrely pulls from your minutes despite the reduced cost of offering voice via your broadband. Early leaked information on AT&T's femtocell pricing shows how much you'll pay AT&T for the honor of improving their cell coverage while using your own bandwidth:

• $20 For customers who only have AT&T Wireless

• $10 For customers who have AT&T Wireless and either AT&T Internet or a landline.

• Nothing if you've got AT&T Wireless, AT&T Internet, and a landline.

Of course for a company that insists that tying promotions to dying landlines is old-school thinking, they're certainly engaging in a bit of old-school thinking here. Tying a bundle discount to landlines when the device is designed to appeal to people moving away from landlines? On the plus side, unlike Verizon's Network Extender and Sprint's Airave, AT&T's service supports 3G connectivity as well as voice.

Update: AT&T tells us that the website is supporting a public trial of AT&T 3G MicroCell service in Charlotte, North Carolina. "One of the things we are trialing is the pricing structure, as you'd expect from a consumer trial," AT&T's Seth Bloom tells us. In other words, this may not be the final pricing, and AT&T will have more detail when the service officially goes national.
