With iPhone OS 3.0 preview coming up within next couple of days, I can share this: Couple of days ago, my friend who works at Apple HQ in Cupertino sent me some of the screenshot for upcoming iPhone OS 3.0. Sadly, attached with the email was also a PDF of NDA, which I had to sign and mail back. Therefore, I can't share the actual screenshot. However, I can describe it to you, since Kevin Rose described it on live Diggnation. (which my friend attended, he's a huge fan of Diggnation) First, the copy and paste. Kevin Rose got that right on! It is exactly how it works. However, Apple, always scared of battery issue, has limited the copy and paste to certain apps, such as Mail, Safari, etc. This is because iPhone and iPod touch uses lot of power on memory, therefore, the copy and paste is limited. But the how it works is exactly how Kevin Rose described it. Now, the background process. The word is that Push Notification was failure. It did not work exactly as planned. Therefore, there will be a limited background support, up to 3 apps (may subject to change). The limit is to prevent iPhone from draining the battery like crazy hell. Finally, redesign of the home screen. Not much changes, except users can now put personal background on the home screen, as well as adding more apps to the dock, expanding the limit from four to about seven, and stacks to organize the apps. This is how Apple will let users organize apps on the iPhone. Now, my friend also sent me shots of what is the next iPhone. Someone already posted this pic, but the next iPhone will have a shell that is full unibody, carved from one aluminum. This means plastic will be gone (hopefully) That's all I can share. Let's hope what I got on the email is right on for Mar. 17.
