has anyone had any problems with their mobileme account not letting them access iCloud? whenever i try to use my apple id/mobileme account for iCloud it tells me that "the iCloud account firstname.lastname@example.org is already configured. press edit to change the account information or press cancel to stop configuring a new icloud account". if i remove my mobileme account completely from the iphone and then attempt to configure icloud, it says that my account has not yet been migrated to icloud". any ideas ?
