Sirius was going to be the SK as far as DD knew. Sirius and Peter 
decided to switch, but they decided to secretly switch. James, Lily, 
Sirius and Peter were the only ones who knew. If the intent was to 
make Peter SK, but not let anyone know, then they must have passed on 
the location in a manner that made it seem that Sirius was the SK. So 
it's very likely a note was used to inform anyone about the location. 

Imagine this. Peter delivers a note to DD with the Potter's hiding 
place. He says the note is from Sirius. For that matter, Sirius could 
deliver it as if he wrote it. "Here's the location," he says.

All the more reason for Sirius's reaction when Peter blows up the 
street. He realises that not only did Peter trick him much earlier in 
the game, but that Peter starting setting him up early on too. 

Now, back at DE HQ, Peter can tell LV. Peter can tell anyone. Or he 
can provide a note. If LV wants a DE to know where the location is, 
but does not want the DE to know who the spy is, he can have Peter 
write the note, and have someone else deliver the note. So if Snape 
was told as a DE, it could have been through a note that he assumed 
was from Sirius.

Back to the IC. One of the older theories here has been that James 
gave DD the IC for the Order's use. DD might not need it himself, but 
the others would. It's possible that an Order member would be told to 
put on the IC and go to a certain area of GH and to report any 
unusual happenings. 

I don't know. That isn't very bangy unless whoever had the IC is 
important. Hagrid? Snape? Lupin?
