WiFi and Bluetooth are probably OK, but I'd be cautious about the radiation emitted by cell phones. I don't think that cell phones are particularly dangerous, but it is really easy to keep them at arms length from one's head. Hands free headsets (both wired and bluetooth) are easy and cheap and make me feel better about this handheld device that emits microwave radiation next to my brain if used as designed. Think about it. Bluetooth device transmits only a few meters. WiFi can transmit maybe 100m. A cell phone datastream can transmit several kilometers. Those are very different transmissions. I think it's foolish to think that there isn't a potential issue with putting a high-powered microwave emitter next to one's head, but with hundreds of millions of phones in use any links will be apparent soon enough.
