I'm the other poster, and I believe you weren't Technically Lying (http://lesswrong.com/lw/11y/not_technically_lying/) but why did you bring up that you hadn't used the driving directions? Maybe this had nothing to do with deceiving people into thinking you weren't associated with the product but I find it doubtful. A more honest self-review (if this really is accepted practice on iPhone) would just say why you think your product is good. It seems you're skating a little over the edge at best.
