Hi everyone. Just uploaded iOS 7.0.2 for iPhone 4s - what a disaster. My Mail app. keeps grabbing old unread emails, that I've already read on primary email via computer. Old OS used to limit incoming emails to 50. I suspect I should just delete my email from this phone in order to clear it up. Any suggestions. I cannot even get the stupid thing to 'mark as read' to all. It's brutal.
