I have an issue and I'm wondering if it is just me. For as long as I have had MobileMe and an iPhone/iPad I have never had my MM e-mail sync right. For example I will get an e-mail at my address and it shows up in the web app and pushes to all devices with no problem. However, if I delete the message in the web app it does not update on the iOS devices until I open the Mail app and have it sync. Similarly, if I delete the e-mail on my iPhone it will take it down instantly from the web app but it won't take it off my iPad until I open the Mail app. Fast forward to today. I downloaded the iOS5 GM and moved my MM account over to iCloud and I am having the same issue. I send an e-mail to my @me.com e-mail account and it comes up in iCloud and the Mail app on my iPad like normal. But if I delete the e-mail from the web app the mail badge still shows the one unread message (also shows up in notification center). I have tried resetting the data on the iPad, restored and setup as a new device, deleted and re-added the account....nothing works. Anyone else having a similar issue?
