Bharara.

A former marketing executive at AT&T pled guilty to insider trading charges after providing sales data for the Apple iPhone and RIM's Blackberry to a so-called expert network, said U.S. Attorney Preet Bharara in a statement.

Alnoor Ebrahim, 57, of Alpharetta, Georgia, pled guilty to one count of conspiracy to commit securities fraud and wire fraud. According to a press release, Mr. Ebrahim was paid more than $180,000 between 2008 and 2010 for providing nonpublic information on handset sales to investors. The charge carries a maximum sentence of five years.

The guilty plea comes after Mr. Bharara's office obtained a guilty verdict in the insider trading trial of Rajat Gupta, the former McKinsey & Co. chief executive charged with passing corporate secrets to now-imprisoned hedge fund manager Raj Rajaratnam.

Mr. Ebrahim's guilty plea marks the government's 63rd insider trading conviction since October 2009.
