Pre-orders for the iPhone Duo begin Friday, giving buyers a chance to arrange protection before the new phones arrive. Cases and screen protectors are available from retailers and accessory makers including OtterBox, Speck, ZAGG, Mophie, Spigen, ESR and Nomad.

Availability varies by product. Some accessories are currently shipping, while others are listed for pre-order and are expected to launch in November or later. That makes delivery timing an important consideration for anyone ordering protection alongside the phone.

ZAGG offers 20% off two accessories

The clearest current promotion comes from ZAGG. Customers can receive 20% off when they buy two items, including eligible iPhone Duo cases and screen protectors. Buying one of each could make the offer useful for shoppers who want complete basic protection in a single order.

Other retailers listed for the iPhone Duo do not generally have broad accessory discounts at this time. Prices and delivery dates may vary by retailer and by specific case or protector, so shoppers should check the listing before placing an order.

Where to find iPhone Duo cases

Several large retailers are carrying cases from familiar brands, while specialist manufacturers are selling their own designs:

  • Amazon: Cases from Spigen, Speck, ZAGG and other brands.
  • AT&T: Cases and screen protectors from Speck, Spigen and others, with discounts listed on some products.
  • Best Buy: Options from Dbrand, OtterBox, Spigen, Kate Spade and more.
  • Burton Goods: Leather cases for the iPhone Duo.
  • ESR: A silicone-and-leather case with a Flex Stand.
  • Nomad: Leather Folio cases.
  • OtterBox: Defender cases.
  • Speck: Presidio cases.
  • Target: Cases from ZAGG, Case-Mate and Kate Spade.
  • ZAGG: Cases and screen protectors, including the buy-two promotion.

What to check before ordering

Buyers should confirm that a case is specifically made for the iPhone Duo rather than a different iPhone model. It is also worth checking whether an accessory is available for immediate shipment or remains a pre-order, particularly if protection is needed as soon as the phone arrives.

Shoppers choosing a case and screen protector together should verify that the two products are compatible. A case with raised edges may offer additional screen protection, while a folio or stand-equipped design can provide different functionality than a conventional protective shell. The available listings cover a range of styles, including leather, silicone, folio, rugged and stand-equipped cases.

With pre-orders approaching, the main options are already visible, but stock and delivery schedules could change. ZAGG's two-item promotion is currently the most direct way to reduce the cost of combining a case with a screen protector.
