Even the Androids have a card reader to download them to your phone or tablet. Never seen a Bluetooth one. There are ones like Spypoint that sent you the picture via text. You don't even have to go to the camera. Works great for cameras that are a long ways away and left out year round. Have a solar battery Spypoint I am trying that I set up end of Oct, still transmitting fine today.
I have not owned one but there is several blue tooth models available. There is one on Kijiji by WGI called Insite Air. I checked out the reviews and they were not great. Stealth Cam has one as well available at CT.
