Keep these notes.

This will only be available to you in Chapter 5. In Chapter 4, you will have learned Ruby's account number for Spy Buy as well as the phone number needed to call them (these two numbers are different for everyone - they are randomly generated each playthrough). Once Chapter 5 starts, head back into Ruby's house (via the chute/tank underground) and head up to Ruby's Study (second floor, door on the left).
Interact with the phone. Hit the speakerphone button to turn it on and dial the Spy Buy number from the TV (again, it's going to be different for everyone). Once you're connected, press option "2" for the Shoe Phone. Enter Ruby's account number to purchase it. Exit outside of Ruby's house (don't take the fishtank back to the underground area yet) all the way until you can see the letterbox from Chapters 1 and 2. Interact with the Letterbox to receive your package. Open up the box to unlock the trophy.
