Apple’s official $79 silicone case for the iPhone Duo is starting to reach customers and stores ahead of the foldable’s arrival, and early users report a setup requirement: the case relies on adhesive strips that must be properly exposed before attachment.

According to users and accessory descriptions cited by multiple outlets, the case is designed in two pieces and includes instructions to peel away protective film on the adhesive, then align each half on the iPhone Duo and press down to ensure it sticks. Sources also note that Apple’s iPhone Duo Folio with Kickstand, priced at $129, attaches differently: it uses magnets and does not require the same adhesive process, though it provides different coverage.

The discussion appears alongside iPhone Duo preorder timing, with preorders opening just before launch and early device deliveries slated for later next week, while accessory stock is already in stores. Reports also describe the silicone case’s materials and coverage, including protection around the camera bump area and outer display while leaving certain parts of the device exposed when unfolded.
