While hungry journalists nibbled on Japanese finger food, suited themselves up to battle one another on the sumo mat and threw back a few drinks, mobile-handset makers and other mobile technologists showed off their latest products.

LG displayed its VX 3450, aka the “Teen Phone” (not to be confused with “Teen Wolf,” the ’80s teen movie starring Michael J. Fox). The new phone, which came out last week, is being sold by Verizon Wireless.

Research In Motion showed off its brand new BlackBerry Pearl phone, now available for use on the T-Mobile network. The Pearl has a very cool design. In fact, says CNET News.com reporter Marguerite Reardon, it’s the first BlackBerry device that looks like a real phone and not a souped up calculator.

Motorola displayed this year’s version of the Audex snowboarding jacket, made by Motorola and snowboarding gear company Burton. The jacket, which comes in pink for women and black for men, is Bluetooth-enabled and allows snowboarders to listen to streaming music from their iPods or Motorola Q handsets. It also allows them to make calls from their Motorola phones while on the slopes. There’s a built-in control panel on the sleeve for changing tracks, checking the ID of a caller or picking up calls. Stereo speakers are built into the collar. The microphone is sewn into to the sleeve for hands-free talking.

MobiTV, which provides streaming video content for mobile phones, was also at MobileFocus, Pepcom’s technology showcase. MobiTV showed off a newly announced service that allows people to access MobiTV channels on their PCs through their broadband connections. MobiTV is partnering with AT&T to offer the service.
