GSMArena reports iPhone Duo silicone case requires adhesive

GSMArena reports that Apple's official silicone case for the iPhone Duo comes with an installation caveat. According to users cited by the outlet who already obtained early iPhone Duo units and bought the cheaper silicone case, the case requires the adhesive on the inside to be exposed before installation.

The article says the case reportedly will not stay on the phone if the adhesive is not used and will fall off easily. GSMArena describes this as the first time it has heard of adhesive being used to keep a case in place and asks why Apple did not use magnets instead.

The report says users who like to change cases or go caseless at times would be forced to stick with the silicone case. It says alternatives include the more expensive folio case or a third-party case that does not require adhesive.
