davidblaineAfter bigger rivals Verizon Wireless and AT&T stole the limelight at the Consumer Electronics Show with promises of multiple advanced phones for this year, now Sprint Nextel is trying to grab some attention with a stunt of its own.

In an intentionally mysterious invitation, the No. 3 U.S. mobile provider says it has enlisted the help of illusionist David Blaine to show the world how “Sprint’s making the Impossible Possible” at a New York Event scheduled for February 7.

Sprint’s promising that the event will be “a lot of fun” but it is mum on whether Blaine plans relive his Times Square encasement in a block of ice or his vertigo stunt in Bryant Park.

Instead the operator, which has been working for years to narrow customer losses, will embark on “yet another industry first.”

Will it finally report net growth in contract customer numbers? Sign an iPhone distribution deal? Make the troublesome Nextel network disappear? Or simply unveil a new gadget?
