[ by Melanie Gretchen ] A limited partner in Phil Falcone's Harbinger Capital hedge fund filed a lawsuit immediately days after the FCC rejected LightSquared, Inc.'s bandwidth application because its signals interfere with signals used for GPS navigation.  For Falcone and Harbinger Capital Partners, which holds a majority stake in LightSquared, 2012 unfortunately is starting out where 2011 left off. The suit, filed by a New York woman, claims that she and other investors were misled about the fund’s decision to put most of its money into LightSquared. LightSquared Investment. Lili Schad of Wallkill, NY, invested invested $4 million with Harbinger.  She claim she and others weren't told that the fund was putting more than 60% of its money into LightSquared - a company attempting to build a high-speed wireless network.  Ms. Schad, who seeks to represent all limited partners in Harbinger Capital Partners Fund I, says she wasn’t informed that LightSquared’s plan to build the network faced serious obstacles from U.S. regulators. All told, Harbinger Capital has sunk $3 billion into the venture. All's squared in love and war. It's likely that Falcone will see more investor lawsuits, unless Ms. Schad's lawsuit is approved for class action. [NY Post, 2/17/12]
