LAS VEGAS -- Tapping into high-speed 4G networks is a real treat, but sometimes a signal is hard to find. The new CellMaps Mobile Coverage app for Android is here to help.

Announced today at CTIA 2013, the Mosaik application lets U.S. Android phone owners see 4G footprints for AT&T, Sprint, T-Mobile, and Verizon in real time. Users can also drill down to see cellular network services in their neck of the woods or scan the overall 4G picture nationally.

A full-size iPad that gets closer to the lean design of the iPad Mini may finally be on the way.

Production of the fifth-generation iPad is slated to begin in July, according to a report from Taipei-based Digitimes.

According to an American Customer Satisfaction Index report issued today, Apple received a score of 81 (on a scale of 100) in terms of customer satisfaction.

While no disruptions have yet been reported, according to the Associated Press, Anonymous has promised to make good on its threats.… Read more

Satellite phones may seem like a niche technology, and in many ways they are. You won't need one while roaming city streets, but they can be invaluable if you're ever trekking far from civilization -- though that didn't stop this guy from using the HTC One on Mt. Everest.

If you're an in-the-wilds type, then Spot has a new option for you. On Monday, the company announced the Spot Global Phone, a satellite handset that promises a voice and data connection in hard-to-reach places.

Though most satellite phones tend to be bulky, the Spot Global weighs … Read more
