NEW YORK (TheStreet) -- Apparently, $3.40 per share was not Sprint Nextel's (S) - Get Report "best and final offer" for shares of Clearwire (CLWR) that it does not own.

Sprint came forward Thursday with a bid of $5 per share, or about $3.9 billion, for the minority shares. A month ago, the carrier said that $3.40 was the most it would pay for nearly 50% of Clearwire's equity. That was before satellite TV company

Dish Network

(DISH) - Get Report

came forward with a bid of $4.40 per share in late May.

Shares of

Clearwire rose 34.5 cents, or 7.3%, to $5.04 on Thursday afternoon

, with some investors perhaps expecting that Charlie Ergen's Dish will come forward with another offer.

Clearwire's board changed its recommendation on Thursday, advising shareholders to accept the offer from Sprint and reject Dish's bid. The company also pushed a special meeting of shareholders from June 24 to July 8.

Ergen has a number of options. The satellite mogul recently withdrew a $25.5 billion offer for a majority position in Sprint, challenging a bid from


. Ergen could renew his pursuit of Sprint.

T-Mobile USA

(TMUS) - Get Report

would be another option. Shares of T-Mobile rose 73 cents, or about 3.3%, to $22.96, on Thursday.

Ergen has also made a $2 billion cash offer for assets of a unit of


through a vehicle called

L-Band Acquisition

, according to bankruptcy pleadings.

Sprint, led by CEO Dan Hesse, holds just more than 50% of Clearwire. The Overland Park, Kan., telecom said that its latest bid values all of Clearwire, including debt and shares that it already owns, at more than $14 billion, or 30 cents per megahertz per person covered by its licenses.

Even though it indicated in May that it would not raise its bid, it would have been difficult for the telecom and backer Softbank to walk away.

Clearwire operates on the same 2.5 GHz spectrum that Softbank uses to deploy wireless broadband service in Japan. Softbank chairman and CEO Masayoshi Son has stated that Clearwire and its portfolio of spectrum licenses are a large part of the Sprint deal's appeal.

"We believe Clearwire shareholders will approve the $5 offer from Sprint regardless of any new overtures from Dish," Walt Piecyk of BTIG LLC wrote in a Thursday note. "Ergen could turn his attentions to Sprint ahead of that shareholder vote next week but it will be challenging given the need to convince a more diverse Sprint investor base."

Shares of Clearwire have more than doubled since early December, when they traded around $2.40 each. Sprint disclosed in a Dec. 13 regulatory filing that its board had authorized it to pay $2.90 per share for Clearwire's minority equity.

On Dec. 17, Sprint announced that it would pick up the minority shares for $2.97 per share.

Dish came forward with a bid of $3.30 per share on Jan. 8. Sprint trumped that bid in May with an offer of $3.30, though Ergen followed with his $4.40 bid later that month.

Sprint said it has the support of Clearwire shareholders Mount Kellett Capital Management LP, Glenview Capital Management LLC, Chesapeake Partners Management Co. and Highside Capital Management LP, which together hold about 9% of the vote.

Including the support of Comcast Corp., Intel Corp. and Bright House Networks LLC along with Clearwire executives and directors, Sprint said it has 45% of the vote.

Minority shareholder Crest Financial Ltd., which has about 4% of the total vote and has vocally oppose Sprint's prior offers, did not have an immediate response.
