8GB iPhone 3G soon to gain an S?

Currently, Apple’s most affordable model of iPhone is the 8GB iPhone 3G, also known as “last year’s model.” But that could change soon. Unconfirmed tips—along with a few, not so blurry, pics—seem to confirm that Rogers in Canada is draining their 8GB iPhone 3G stock to make way for the new 8GB iPhone 3GS. I think it’s fair to assume this rumor would apply to AT&T and elsewhere too.
