T-Mobile's Busy Monday at CES

NEW YORK ( TheStreet) -- Monday was a busy news day for T-Mobile ( TMUS) at the Consumer Electronics Show in Las Vegas.  Sony ( SNE) announced its new waterproof Android flagship phone is coming to T-Mobile. So is the first curved-screen model from LG. And then there was T-Mobile's CEO being thrown out of rival AT&T's  ( T) posh party Monday night.

T-Mobile shares were off 0.14% at $33.34 in early morning trading in New York.

The new Sony Xperia Z1s shares many of its features with 2013's Z1 phone including a 5-inch, 1080p display, a 2.2 GHz, quad-core, Qualcomm ( QCOM) Snapdragon 800 processor, 32 GB of built-in storage, a 20.7 megapixel camera and a big 3,000 mAh rechargeable battery.

But the big new feature of the Z1s is waterproofing. That means the handset has been designed to survive being submerged in as much as 4.5 feet of water for half an hour and can be used to take underwater snapshots. All the phone's ports are protected by tightfitting covers while the headphone jack is available for a user's listening pleasure when he ventures near the water.

The new handset also comes with Sony's PlayStation app as well as upgraded photo software.

Sony's Z1s will be offered for $528 without a contract or $22/month under T-Mobile's retail sales plan beginning Jan. 22.

T-Mobile has also confirmed that it will be one of the first U.S. carriers to offer the new LG G Flex Android smartphone. The handset is the first to market with a flexible 6-inch curved OLED display. The G Flex also sports a 13 megapixel camera on the back and a huge 3,500 mAh rechargeable battery. T-Mobile promises it will share pricing and availability information in the coming weeks.

The No. 4 U.S. carrier also made news when its CEO was thrown out of a party being hosted by No. 2 carrier AT&T ( T). According to a Twitter posting by a CNet reporter, CEO John Legere, wearing a pink T-Mobile t-shirt under his jacket, was "escorted out" of the big CES after-hours event at The Palms in Las Vegas.

Legere, recently a very vocal critic of rival AT&T, was said to have secured passes for the event through performers working the party.

He has promised T-Mobile will be announcing some "big" news at its CES press conference on Wednesday.
