The High-Speed part of the specification is not mandatory, and hence only devices sporting the "+HS" will actually support the Bluetooth over Wifi high-speed data transfer. A Bluetooth 3.0 device without the HS suffix will not support High Speed, and needs to only support Unicast Connectionless Data (UCD), as shown in the Bluetooth 3.0+HS specification, Vol0, section 4.1 Specification Naming Conventions.
