Well, I just got my iPhone 4 this last weekend, and I think it's the bee's knees.

I can make the bars change by touching the iSpot too. But interestingly, I seem to be able to make the bars go up when touching the iSpot just as often as I can make them go down. Radio frequencies are just weird that way.

Does that make an external touchable antenna a good design or a bad one? Meh, I don't care, the thing works for me. It's got some great features and it performs well.
