With Day 3 of the International Consumer Electronics Show in the books, let's look at the five things we learned.

1. T-Mobile targets termination fees

Turnsout T-Mobile CEO John Legere's dust-up at an AT&T party was just aCES appetizer. The main course would be served at a company eventWednesday, where Legere revealed what he calls his "get out of jailfree" feature.

T-Mobile will offer to pay early termination feesto users who leave AT&T, Sprint or Verizon, so long as you trade inyour phone and get a T-Mobile plan. But the carrier claims it will offerback as much as $650 per line for up to five lines.

The event caps an interesting week for Legere, who made news aftergetting booted from an AT&T party. As he told the tech site Re/code:"I just wanted to hear Macklemore."

2. Wearable tech goes to the dogs

Fitness bands aren't just for humans. Tech company i4C Innovations created the Voyce for dogs, which they wear like a collar.

Thedevice tracks key vital signs and calories burned, so users can get agood reading on how active their four-legged friends are during the day.Voyce can sync to your computer, smartphone or tablet through Bluetoothor Wi-Fi. There's even a built-in social network where users cancompare their pets' data with others.

But don't expect it come cheaply. Voyce costs $299, and that's not counting a monthly subscription fee.

3. Here come the curved TVs

Those Ultra HD TVs with curved displays may be hitting stores sooner than we thought.

Samsung's HS Kim, VP of the electronics giant's visual displays division, says two models of curved UHD TVs will hit the U.S. during the second half of the year.

The105-inch curved set and an 85-inch bendable Ultra HD TV will launchlater in 2014. No prices have been set, but expect to pay a smallfortune to own one. For perspective, Samsung started selling a 110-inchUltra HD TV in South Korea for $150,000.

4. Beamers go all-electric

Car tech has been huge at CES this year, and BMW is among several automakers touting technologically advanced vehicles.

Itsall-electric i3, available in May for $40,000, can go for about 100miles before drivers need to recharge. The other interesting part,according to USA TODAY's Jefferson Graham: "Take your foot off the gaspedal, and the car nearly stops."

BMW product manager Jose Guerro says the i3 is aimed at commuters living in big cities.

5. Pandora plays on

Competition in the streaming music business has been fierce, betweenthe arrivals of services such as Spotify, Rdio and - most recently -Apple's iTunes Radio.

However, that hasn't stopped one of theearliest music streaming services: Pandora. The service continues tochurn along - with 76 million active monthly listeners in 2013 - as itnow aims to become more integrated with the car.

Nine of the top10 selling passenger vehicles host a Pandora app, and the company ismeeting with automakers at CES to expand. "It's a massive category,"says Pandora CEO Tim Westergren.
