US probe into Verizon's might

<div>THE US Justice Department has begun a review of big telecom firms such as AT&amp;T and Verizon, to determine if they have abused their market power.<br /><br />Sources close to the matter said that the Antitrust Division's probe could concern exclusive agreements between phone companies and handset makers or whether phone operators are &ldquo;unduly restricting&rdquo; services third parties companies can offer on their network. AT&amp;T spokesman Mark Siegel said he was not aware of any formal probe, but declined to comment on any informal proceedings.</div>
