While

and

slug it out for first place,

Sprint

(S) - Get Report

is vying against T-Mobile for the last place among the top four wireless telcos.

Sprint was nearly undone by the

Nextel

merger, which took a toll on the company, its subscribers and its profits last year. This year, Sprint's recovery hopes are

pinned largely

on

Palm's

( PALM) Pre, the hotly anticipated touchscreen smartphone.

Deutsche Telekom's

( DT) T-Mobile USA has been the sector sleeper steadily gaining customers through inexpensive calling plans and a few fun phones.

T-Mobile's modest success is due partly to

Research In Motion's

( RIMM)

popular BlackBerry phones

. In addition to the BlackBerry Flip Pearl and the Curve, T-Mobile is expected to get another 3G addition to its lineup, sort of a sleeker version of the Curve and Bold.

T-Mobile has also benefited from

Google's

(GOOG) - Get Report

Android-powered

HTC

G1 phone. And, if reports are true, the second version of the phone, dubbed Magic, will land later this year.

The other potential product hit for T-Mobile this year is the

Samsung

Memoir. This eight-megapixel camera is also a touchscreen phone that can surf the Web.

T-Mobile is one of the fastest growing-business units of Deutsche Telekom's empire.

For Sprint investors, the races with T-Mobile and even the Palm Pre are secondary to possible takeover prospects. Spain's mobile giant

Telefonica

(TEL) - Get Report

is preparing to make a big impression in the U.S. As

TheStreet.com

reported Friday, Telefonica is

looking to hire a publicity agent

to handle its image in the U.S. and U.K.

The move signals Telefonica's interest in expanding its global footprint beyond Europe and Latin America. Sprint appears to be the prime buyout candidate as the company tries to regain its footing after a crushing 2008.

Without a buyout, Sprint is left with a limited-term exclusivity agreement to sell the Palm Pre and its alarming customer defection rate.

Sprint has 50 million subscribers and dropping. T-Mobile has 33 million customers, and that total is rising.

Sprint shares rose 5% and Deutsche Telekom fell 2% at the close of trading Monday.

At this rate, Sprint will need a merger and a blockbuster performance from the Pre to avoid losing more ground to T-Mobile.
