iPhone Notification Thoughts

Apple created their Apple Push Notification system to allow applications to present information to the user, even when the applications are not running.  This helps reduces the amount of CPU usage on the phone, which will help prolong battery life

I would like to see a few things added to this:

  • Better support for multiple notifications.  Currently only the last notification is shown. There are a few things that could be done

    1. Create a view that aggregates all of the new notifications since the user last looked at the phone

    2. Create a prioritization scheme that would make sure that the most important notifications are visible first

    3. Allow developers to expire previous notifications for their applications



  • Support to send information back to developers.  Since using Apple's Push Notification requires  developers to have a server that keeps a persistent connection with Apple's servers.  This connection could be used to send information from about the iPhone back to developers

    • For example, this could be used to send location data back to developers.  This would allow Loopt or Google Latitude to update a users location without running an application in the foreground.

    • Having this implemented in  this manner, it would allow the users to have control over this data

      • Users should be able to go to settings application and disable this feature for all applications, or for particular applications

      • Apple could control the frequency that the GPS would be turned on, so they could conserve power appropriately.

iPhone 3.0 and USASpec adapter

As I have written in my previous posts, I have been pretty happy with the iPhone 3.0 update.  I have been experiencing one annoying problem.

When I connect my iPhone 3.0 to my USASpec PA15-HON2 adapter that is installed in my car, the iPhone stops playing audio and the screen flashes for about a minute, before audio starts playing.  Here are the steps that I use where the problems occurs for me

  • Play a track/playlist

  • Connect the iPhone to the dock

  • => The Radio switches to the cd changer input (correct for my setup)

  • => The screen in the iPhone continues to flash the iPod graphic for about a minute

  • => After about a minute a different track starts playing


Once music is playing, the interface works perfectly.  It will continue to work, until I disconnect and reconnect the iPhone.

I think that the iPhone 3.0 software added some addition scanning that happens when connected to this adapter.

Other iPhone 3.0 features

I just noticed some other feature that I believe were added in the iPhone 3.0 software, that I don't remember seeing posted anywhere else

  • 30 second skip back.  When playing a podcast, there is now a button to skip back 30 seconds.

  • Adjustable playback speed - When playing a podcast, you can now change the playback speed to 1/2x or 2x, in addition to 1x.
