From the National Journal: LightSquared said on Monday it will move to a different spot on the spectrum to avoid interfering with sensitive GPS. The company says it can move to a spot that it had reserved for later expansion.

Last week, LightSquared asked the Federal Communications Commission for extra time to answer questions about whether its proposed wireless network might interfere with GPS signals.
Tests have shown that wireless signals from LightSquared's planned network interfere with GPS receivers used by the Federal Aviation Administration, police, firefighters, the Coast Guard, and NASA.
