Tw.Apple.Pro has published some design drawings which they believe to be for the next generation iPhone. The drawings aren't particularly revealing but they draw comparisons to the leaked iPhone parts video that was posted earlier this week.

That video was removed from YouTube at the demand of Apple, suggesting the contents were legitimate. The video showed that the break points in the frame between the two antennas have been moved to different locations, indicating that the antenna design has been tweaked despite a very similar overall appearance for the new iPhone.

Apple legal will have these drawings down by tomorrow morning.

Looks legit. 3 band parts instead of 2 suggests 2 separate antennae GSM + CDMA plus Bluetooth/WiFi

New/more separator splits in the antenna band so that they could put more antenna signals. Dual CDMA/GSM anyone?

Looks like the new antenna has four separate pieces as opposed to the previous two:

Nothing to see here folks, move along. Not a major re-design by any means. Just some fiddling with the antenna's placement.

Most likely an incremental update. iPhone4 is an incredible piece of technology, engineered to perfection. It's unlikely to see any dramatic change anytime soon.

This looks to be akin to the iPhone3G to iPhone3Gs update. Faster processor, more memory, tweaks to the antenna to prevent the death grip, and the use of updated/smaller components.

Time is up for the exclusive AT&T contract so dual CDMA/GSM support is likely, rather than separate phones.

or instead, the top and bottom of the iPhone will become nothing, and only the sides will be the antenna, that way you won't be able to attenuation the antenna by putting your finger between the black splits/dividers.

wasn't that the issue, by putting your finger on that 1 spot of the phone you joined the antennas together causing it to loose signal?

Makes Sense

Makes sense to me ... I'm not an engineer, but I would think putting the antenna at the top of the phone would have made the most sense and reduced overall interference.

Here is to looking forward to a great revision of a great product!

The Drawings...

Match the central plate of the video... this is because of the camera, now surface mounted, and the central plate holes in the drawings matching those in the video...
Also the redesign of the wire to the longer one in the video matches the separation of the external aerial.

Also when you look on the video the frame screw positions have shifted so there is a separate band on the top which matches the new wire length...

Kind of obvious...

...but, it should be mentioned that the drawings could have been done by the same person who filmed the earlier YouTube video.

I could see the bottom becoming nothing and fixing the issue but that would still leave the piece at the top for using another signal type.

I am more curious on what the iPhone 6 will look like. We know the 4 was in development for almost 2 years.

Except everyone cries foul when the antenna is located right next to your head. That's why they are usually located at the bottom of phones which use an internal antenna design.

Keep 'em coming, all this news about the next iPhone is great news since i skipped the iPhone 4.
I'd really like a better battery life and processor, more than anything.

N90 = iPhone 4?

VERY GOOD POINT! I may have to eat my words on this being an iPhone 4 prototype part.

SUPPOSEDLY the CDMA iPhone is coded N92. These documents say N90.

I'll be watching this closely to see how it turns out. Very curious stuff going on here.

Edit: Looking more closely, I'm seeing a date as well. 2010 7 29 (Upper right of 3rd pic...right above the N90 designation). Can't make out what the red stamp says.

It would also radiate more RF energy right into your brain, and thus have a higher (and much less desirable) SAR rating. The antenna at the bottom configuration is an attempt to radiate microwaves away from your head, not directly into it.
