    I have one question about Apple's new iPhone 4 antennas.

    Is the black seams antennas which becomes part of steel frame or are they just there to separate the two other steel parts from one another, with no other function?

    the seems are there to ruin our pre-conceived notions of what constitutes apple design!!! oh noes!

    but seriously, i think they are there to separate the the antennas. if there was only one radio i don't see why they couldn't have made it one continuous piece.

    Steve Jobs addresses this very question in the Keynote. It's worth a watch.

    He did not say if the seams was just to split them or if they are antennas?

    i saw the keynote, i remember there being a graphic that showed the two antennas split apart, right where the seams were.

    Well, a seam joins two things together...so the things being joined together are the two pieces of the antenna.

    There are only 2 antennas, but 3 seams. One is a dummy seam added just for symmetry. They should have put a seam at the middle top and another seam at the middle bottom which would be less obtrusive.

    Lol, the top seam is the real one. And the bottom middle seam..? Over the 30 pin port?

    Antenna Gain?!?

    I don't understand if the metal ring on the outside are really the antenna how does the iPhone 4 deal with things like resistance shift and parasitic attenuation when in comes in contact with the human body.
