Lightspeed Leapfrog is an entire trope of its own... can you look through the examples and see if any of them match what you're looking for? If not, you're going to have to provide us more details.

Sounds like "The Shoulders of Giants" by Rob Sawyer. http://www.sfwriter.com/stshould.htm

I think it was a short story. The plot is that a habitable planet is discovered, and a colony ship is sent there, with the colonists in cryosleep since they won't be there for centuries. However, before they get there (but hundreds of years later), FTL Travel has become possible and the glaxy is much more populated, including the one the ship was headed on, and the colony ship is now basically useless.
Does that ring any bells?
