Theres also the option of going to best buy, since they will 100% have the white 5S unless out of stock. Koodo is available in best buy mobile so you can get a white 5s with a koodo plan all at best buy.
btw if you guys have not noticed... phone come already locked to their carriers.. in best buy... they have an order sheet and for Koodo as of now today.. there is only space grey! don't believe Daniel Kim
Koodo might or might not have the other colors but Telus does and will the Telus model not work on Koodo without unlocking it like the last 3 or 4 iPhone's?
Just an option besides waiting to get other colors from koodo or instead of ordering from Apple directly.
