2.5 mm headset adapter for iPhone
I've just gotten an iPhone 3G, and it's great to be able to use normal headphones without an adapter. There's only 1 catch: how do I use my old cell phone's earpieces with it? Is there an adapter that goes from the 2.5 mm 3 contact plug that the cell phones use to the 3.5 mm 4 contact plug used on the iPhone?
If you happen to know where I could find such a thing in Canada, that would be very much appreciated!
