iPhone application developer tap tap tap shared this wonderful video of their Convert (iTunes link) app’s design evolution on their blog recently. This kind of attention to detail is why we love iPhone apps and their developers so much!
When invoking the application organization mode in iPhone OS 3.0, you can now shift through multiple pages in a direction simply by holding the app to one the other sides of the display.
Previously, in iPhone OS 2.0, you had to move the app to the edge to invoke a page shift, then move it slightly away and back again to shift another page. This typically caused applications on each page you shifted past to get rearranged, which was especially irritating if you have a lot of full pages.
In iPhone OS 3.0, you can simply hold the app to either side of the device display to keep switching past pages; no organizationally destructive back-and-forth teetering required.
Voice Control in iPhone OS 3.0 took over the iPhone’s “press-and-hold the Home button to do something” ability, so the method to force-quit a stuck app has changed. Now you have to hold the power button at the top as if you’re powering down the phone. When you see the red slider, hold the Home button for a couple seconds. You’ll be taken out of the power down mode, and if all goes well, your app will quit.
