I just recently got a new iPhone. I didn't have this problem previously with my old iPhone. Both iPHone 4s. When I delete an email off of my iPhone, it also deletes it on the email server.. So when I go to my email from my computer, that message is deleted. I've looked up how to fix this, and it includes going to your email account through settings in your iPhone, and then going to "advanced." Well there IS NO ADVANCED OPTIONS. I'm beyond frustrated at this point. I do not want my emails to be deleted from the actual account when I delete them from my iPhone.
