A court has ruled that Verizon can continue to air ads attacking AT&T’s 3G coverage. So how does AT&T respond? By airing its own anti-Verizon ads of course.

Legal documents are traditionally filled with jargon, gobbledygook, legalese and wishy-washy language full of ifs and maybes. But not the latest filing by Verizon.

Dell has confirmed it will be releasing an Android-based phone in China and Brazil. But it’s not giving out much technical info or saying anything about reported plans to release a handset in the U.S.

There’s a growing theory that the model for computer hardware will eventually follow that of mobile phones: hardware costs subsidized by communications service deals. Following several similar deals by netbook producers, Nokia has adopted the tactic by offering a Windows 7 laptop for $299 to mobile broadband customers.

The Federal Communications Commission is investigating claims that Google’s Voice service is breaching regulations by blocking some calls to rural areas. It’s reopened the debate about the way traditional phone networks and those which carry voice calls over data connections are regulated.

It was perhaps inevitable that AT&T would eventually carry an Android phone, completing the system’s sweep of the major US networks. But it comes from an unlikely manufacturer: computer giant Dell.

In a change of policy AT&T will now allow iPhone applications to use its data network for voice calls. The decision, possibly influenced by regulatory pressure, could cost it as much as $20 a user each month.

With Windows Mobile 6.5 launching today, manufacturers are unveiling their first handsets designed specially for the system. In the U.S. that includes three HTC models plus a new Samsung device.

Although Apple turned down the Google Voice app, it appears the firm isn’t opposed to all attempts to avoid using AT&T’s services. It’s approved an app which allows cheap rate calls via the voice connection as well as over the internet.

A new handset running on the AT&T network is the first to combine standard cellphone service with satellite radio. It means the handset will fit in your pocket but make calls even in areas with no cellphone reception – but at a price.
