Well I got the iOS 5 GM installed on my iPad today and went to setup iCloud on it but I decided to use my expired MobileMe account with it so I can access my email again (I still used the account for apps and Find My iPhone) it all went seemingly fine and Mail was shown as activated so I went onto the mail app and it didn't sync any mail. Weirded out I decided to try and log into the account in Mail on my Mac but it said the username and password were incorrect (something along those lines) so then I went to safari and typed in iCloud and logged in via the web apps but mail still doesn't work and acts like it crashed and wants me to send a report to apple? everything else just works and syncs normally except Mail and that was the whole point of me wanting to use my old @me.com address. This is really getting frustrating!
