Not sure if you know the MyBlu from Mavizen. I use it on my iPods to take calls from my main Nokia. I'd like to do the same with the iPhone - i.e. use a similar device as a remote... but also for it to act as a wired headset for the iPhone. The end result being that I can listen to the iPhone but take calls as well, but also take calls coming into the Nokia via Bluetooth - all via headphones of my choice, using the mic built into the remote. Does such a device exist? *Ideally I'd like it to pair with another iPhone as well via Bluetooth in addition to the above, so that I can field calls from a Nokia + 2 iPhones with a single headset/remote.
