I'm still on the fence about buying the snap-in adapter because I think it is way overpriced. (the adapter cost more that the iPhone 4) I am curious about the external antenna function though and I can't find anything on the web showing support for an external antenna but that doesn't mean it doesn't work. If someone has the adapter and is willing to test it for us, you can put the iPhone into field services mode to get the exact signal strength using the snap-in adapter and without. When in field services mode it with show the exact signal strength in DB. Here is a short article showing how to get it into Field services mode.
