Correct, because Android does not request the full MIME message (only  
the plaintext body), whereas BB is requesting the full MIME structure  
(AirSyncBase:Type value of 1 is plain text body, type or 4 is the full  
MIME structure). What's probably happening is I am truncating the MIME  
stream before sending it, which obviously breaks it. Instead, we  
probably need to send only the MIME headers in the stream data along  
with the WBXML attachment structure if the total size is greater than  
the requested MIMETruncation value.  I'll look into this further, the  
log helped.
