Before I begin, one critical clarification.  When you say "soundmodem", 
do you my Tom Sailer's soundmodem or UZ7HO's soundmodem?  If we are 
talking about Tom's version, yes, almost all of the sound card TNCs in 
my URL offer better decodes.  Some also offer alternative modes from 
just say AFSK 1200 and G3RUH 9600.

Soundmodem wasn't decoding things or PocketPacket?   I know nothing 
about this iPhone app but I do know that Tom Sailer's soundmodem only 
can decode about 40% of the packets that Direwolf can.  Read Direwolf's 
appendix in the User Guide for full details.  There, it compares 
Direwolf, UZ7HO Soundmodem, Tom Sailer's Soundmodem, Kantronics, TNC-X, 
etc.  Very interesting read!
