Just received my iPhone 4s today and having some issues with the address book. My address book in iCloud is an import from my previous exchange server. Works fine everywhere (Lion, iCloud.com & iPhone Contacts) but fails when using Siri. It looks like the fields where phone numbers are stored are a different format that Siri doesn't recognize. Siri pronounce the mobile number field as in the screenshot. Anybody having the same issues and found a workaround or easy way to convert all the fields to native iOS fields? Luv my new iPhone btw.
