Where are the iPhone 4 antennas' feeding and grounding points?

What sort of antenna does iphone 4 employs? Is it an IFA (inverted F antenna)? I tried to find the feeding and grounding points, particularly for the wireless antenna (WiFi, Bluetooth and GPS).

Usually and IFA has a feeding point somewhat in the middle. Unfortunately, I cannot find it. There seems to be a feeding point close to the top slit.

Is it possible then to achieve dual-band behavior? How many grounding points are there, and where?

thanks
