Maybe I didn't word things clearly. I agree emailing Samsung is a waste of time. Posting on the T-Mobile website however might make something happen. They seem to care a bit about customer service and won't want lots of negative posts all over their forums. If we all claimed to be Behold II users who are angry that myTouch is getting Froyo and we're not (together with genuine Behold users) there might be enough noise for them to push Samsung, cos we sure as hell cannot.
Looking at their forum earlier there was just one post about it hidden away, if there were 100 - 200- - - 500 posts who knows...
