Solution for iOS4 on iPhone 3G

Steven Cogswell

After much experimentation and research, I’ve determined how to fix iOS4 running on the iPhone 3G. No warranty is expressed or implied. YMMV.

Preparation:

  • First off, make sure you’re updated to iOS 4.0.2
  • Make sure your phone is backed up, and do two hard resets (holding down the sleep button and home button until it resets).
  • Then do a normal power off (hold the sleep button, slide to power off). Wait 30 seconds and power back on
  • Do a DFU restore of iOS 4.0.2
  • After you’ve done the restore, don’t restore from the backup. Reinstall all your applications and re-enter all your data. Don’t sync any music yet.
  • Backup the iPhone again

The Important Part:

  • Put every application into Folders. Not just willy-nilly. It’s important that you put all the applications of the same category into the same folder (i.e. – All the “Social” applications in one folder, all the “Navigation” into a different folder). I’m not sure if you should have them sorted alphabetically in the folder, but it can’t hurt.
  • Go to Settings -> General -> Home Button -> Spotlight Search and turn off Spotlight for everything except Notes.
  • Turn off Push Notifications. Wait at least 15 minutes for the servers to catch up. Then turn Push Notifications back on
  • Sync your music. Use iTunes to sync the “only checked songs” and then incrementally sync the iPhone by genre (i.e. – check all the 50’s music, and sync. Then check all the 60’s music, and sync. Check all the Pop music, and sync.). After each Sync do a power off-power on sequence.
  • Convert all your videos to h.264, but make sure you’re using Main profile with 8 b-frames, CABAC, and CQ mode of 19. Use FFMPEG. It’s actually pretty easy to write a bash shell script to do all this, so I won’t bother including it here. Make sure you get all those little options right
  • If you have ringtones, make sure none are longer than 29.97 (30p) seconds, and none shorter than 23.976 (24p). Use Garageband or Audacity for this
  • Give up on iOS4 on the 3G and get an iPhone 4 instead, nothing’s going to fix that bullshit.
