Apple’s official iPhone Duo case (AED 319) needs adhesive to stay on; know this before October 23

Early iPhone Duo recipients found that Apple’s official "iPhone Duo Case" ($79, AED 319 on Apple UAE) ships with an internal adhesive layer you must expose and press onto the phone; without it the case falls off. The product page talks about MagSafe magnets and never mentions adhesive. The official alternative is the Folio with Kickstand at AED 529.
