Not sure on lambda but I was always told that the best way to store say
M13 phage was to filter sterilise phage in media and just store that at
4C. I have M13 phage stocks going back over ten years that were done
this way and so far they are still very alive.

For lambda, CsCl stocks (again stored at 4C) seem to be viable for many
many years.

The problem with being on the cutting edge is that you occasionally get 
sliced from time to time....
