It would be nice if the the next generation iPhone would come with a RF transmitter. That way it could replace my garage door opener, car security alarm remote, remote to open my van door.... the possibilities are just endless. It could even be used as a TV remote. The Delphi software that showed an iPhone showing a vehicles diagnostic's was great.
that is actually a pritty kewl idea, wich at some point im shurr thats were the phone world will be headed. seems like we are gradually gettting closer to a device that does it all. slices and dices and makes mac&chees baby!
You can buy a 3rd party solution that enables bluetooth communication. The iPhone can already open garage doors etc. The problem with that is that you would have to connect to the device before it worked, which would take time.
