Cases for the Blackberry Bold come in many styles, including open face, book style, and wallet style. They help protect the Bold and give it some personal flair. The Bold comes with a removable black leatherette cover.

For many users, the case is an important accessory for any smartphone. Flexible silicone cases, like the ones from OrionGadgets, are a good choice for users looking to keep the Bold free from scratches. Users looking for something sturdier may like the molded silicone cases from OtterBox, which can protect the Bold from damage by absorbing impact. However, for the business user, a leather case adds some professional cachet. Piel Frama has a hand-tooled leather case for the Bold which comes in several colors. Case-Mate also has a Signature Series leather case, which is wrapped around an impact resistant molded shell.
