frequency analysis on a simple substitution type cypher should never fail.
it was close. but the trick is the frequencies on short messages only give you probabilities that a certain mapping is true.
but those probabilities are enough to shorten the potential mappings significantly (i.e. e is probably e or t, g is probably e or t).
Combine that with a word match (does the result contain stop words such as - it not the etc)

and bam, game over.
