In an effort keep the troubled LightSquared from the brink of defaulting on its debt, its founder will step down from the company. While it doesn't look immediate, (people "familiar with the negotiations" are using the word "eventually") it's Philip Falcone's latest attempt to extend a debt-term violation that expires this morning. According to the same sources, if the initial extension is okayed, Falcone and LightSquared's lenders are aiming for a greater period of around 18 months to repay $1.6 billion in loans and pass the FCC's requirements for its network. The company's board is still deliberating on whether to accept the deal, which would stop the company filing for bankruptcy protection. Unfortunately, it looks like those new 4G network dreams just got hazier.
