It starts like this:

0000000: 474f 5244 1802 0000 0000 0000 1800 0000  GORD............

Unfortunately, this isn't an Apple II SQ file.  Comments from NuLib2's
Squeeze.c:

 * The SQ file format begins with this:
 *  +00  magic number (0xff76)
 *  +02  checksum on uncompressed data
 *  +04  filename, ending with \0
 * The NuFX format skips the above, starting immediately after it:
 *  +00  node count
 *  +02  node value array [node count], two bytes each
 *  +xx  data immediately follows array

The file itself might be a data file from a T-Mobile Sidekick (developed by
Danger Research in Palo Alto, CA), and does not appear to be compressed.
It looks like they use a "chunk" format, where they have a 4-byte text
chunk name followed by a 4-byte little-endian length (except in cases
like "AD32" where the length is implied -- perhaps an Adler32 checksum?).
This is a pretty common way of doing things.

If it is what I think it is, this is a fairly recent and probably
proprietary format, and Apple II utilities aren't going to help.
