Apple's Worldwide Developer's Conference wrapped up at the end of last week. The conference kicked off with a flurry of announcements surrounding Apple's new iPhone 4. The response to those who had actual hands-on time with the upcoming iPhone has been overwhelmingly positive with a particular focus on the high quality of the display. Several people we spoke to echoed Steve Jobs' comments that it will be hard to go back once you start using the 326 dpi display.

This weekend Robert Scoble posted high resolution photos comparing the new display to the existing one (iPhone 4, iPhone 3GS). The images clearly show the increased readability of web pages while fully "zoomed out". Macworld's hands on also echos the sentiment::
We placed an iPhone 3GS and an iPhone 4 side by side. The results were readily apparent. Text on the iPhone 3GS, while quite readable, showed noticeable pixelation. We couldn’t pick out any pixels on the iPhone 4’s text; as Apple claims, this screen really makes text look like something you’d find in a book or a magazine, with none of the artifacts that we’ve come to expect from a LCD display.

Apple has claimed that the new display exceeds the limits of the human retina. While there has been some debate about the accuracy of these claims, at least one expert considers the claims close enough to reality.

For another point of reference, Apple provides this actual screenshot of an iPhone 4 screenshot. Click to see it at full resolution:

Of course, this same image when viewed on an iPhone 4 shows the same number of pixels but within the space of a 3.5" display.

HSUPA Support

Meanwhile, iLounge has noted that the iPhone 4 supports 3G HSUPA (High-Speed Uplink Packet Access) for its uplink. iLounge cites a theoretical maximum of 5.76 Mbits/second. Meanwhile, the iPhone 3GS is limited to only 384kbps. Any faster uplink speeds will obviously help out in emailing high definition video clips over 3G networks.

If this is not good news, then what is....

sounds awsome. looking very much forward to it....

Even better news would be Holland beating Denmark, but that is not apple related.....
 
Increased upload speeds welcomed, however, with the removal of unlimited data, we're going to be restricted to what we can send now. At the point hi-def video comes to the iPhone, data transmission is restricted... :mad:
 
This new display would make the iPad even better than the great product it already is.

Can't wait to get the new phone - 8 days left! :D
 
If that display doesn't make it into the iPod touch in September there will be copious amounts of heck to pay. It looks outstanding.

So true, the data cap is lame. I remember when the original iPhone came out Steve made a BIG DEAL of saying how he fought for unlimited data so people could use their iPhone without any worry. He wanted the best experience. Not anymore!
 
Dare I say, who gives a crap about the i-devices, whats up with the XCode 4.0 that is in the works and when are we going to see it released to the unwashed masses? hopefully XCode 4.0 will provide the grand unifier between iOS and Mac OS X programming so that an application can easily be run on the desktop, laptop or the hand held device. Oh well, maybe the good news about a Mac OS X dedicated WWDC turns out to be true and we'll see Mac OS X given some more love next time around.
 
A lot of the debate about the 'retina quality' claims is based on the theoretical mechanical limits of what the eye can see. I doubt anybody's eyes, however good, reach these limits in the real world.

During my psychology degree in the late 90s, I spent some time learning about the eyes (as a major path of input to the brain) and we were always taught the 300dpi figure Jobs uses. This figure was not based on theoretical engineering principles, but on actually testing what people could see.
 
iPhone 4

I have iOS4 installed on my 3GS and to be honest looks great so looking forward to the new iPhone 4, just hope I get a good upgrade price :D

5.76 was mentioned in the Keynote. Not all networks support HSUPA 5.76, but virtually all support 2Mbit.
 
The display is better but all the marketing garbage is tedious. The new display does seem to have some limitations based on that photo - you can see the m+i in 'minutes' merging into one due to a lack of pixel space and the i+o in 'Commission' are joined at the hip too.

It's a 3.5" screen. Don't expect miracles, of course some letters will be smashed together, it's amazing it's as detailed as it is.
