Activision's Sin page has posted the version 1.03 update for Sin. Here's a local copy (2.0 MB) with a mirror courtesy of our pals at Walnut Creek CDROM. Here's the lowdown on the new patch, which offers compatibility with the new Wages of Sin mission pack:

This patch updates your previously patched version of Sin from 1.01 to 1.03. You must have at least version 1.01 before running this patch. If you have not previously patched your Sin game, download "Sin Update 1.01" and run that first.

There is one inclusive file named sinupdate103.exe, it's a 2 meg download taking 10 minutes from a 28.8 kbs.
