Well, kids, we don't know if this is a typo, a Freudian slip, or both (or neither), but according to this handy graphic on Rogers' website the rumored 8GB iPhone 3GS exists -- if not for sale, at least for comparison. Keen readers of charts will note that the price listed for the 3GS still starts with the 16GB model, and if you scroll through to the ordering page there is no 8GB 3GS option listed. So, what do you think? Do we have a promising development here, or a simple case of a misplaced check mark? Feel free to sound off in the comments.
