Sweetest Thing IS released in Canada

I'm not sure if this has been posted, but both versions of The Sweetest
Thing are released in Canada, I picked up mine today.

Also, (again, I'm not sure if this has been poseted) I heard on the
radio that Bono wrote this song because he missed Ali's b-day...but (the
radio hosts) suspect that he might have cheated, so to speak,

is this true?
