This answer applies to R2i Mk2
R2i works with iPhone, Touch and Nano models with Lightning connector, but an adaptor is required which is available directly from Apple and many Apple resellers. You can view this device here. We also recommend that an Adaptor Support such as the one shown here is used in order to avoid strain and possible breakage of the 30 pin dock connecter.
