When you dial 3001#12345# on an iPhone, it brings you to field test, which gives you cellular info and stuff like that. If I got the source code for this, would it be possible for me to turn it into an app using Xcode that I could just open from my home screen. It would be much easier than dialing that every time.

iOS field test




Field Test is already an app: /Applications/FieldTest.app!

The app icon is just hidden on the home screen, and the Phone app launches this app.

If your iPhone is jailbroken, you can edit the application Info.plist to show the icon on the home screen. In /Applications/FieldTest.app/Info.plist, edit SBAppTabs array to remove ‘hidden’, then run uicache as mobile.

  • Thank you! My phone is jail broken, so I think I’ll try that. If I wanted to, could I also sign it through Xcode? – user295021 Apr 2 '18 at 19:26
  • I can’t seem to find an info.plist file in the fieldTest.app, is there something wrong? I’ve included a photo in my original question above – user295021 Apr 2 '18 at 19:30
  • @user The 7th row in the picture of Filza is named "Info.plist"? :) (Don't forget to make a backup of the file) – grg Apr 2 '18 at 19:34
  • Oh gosh I feel stupid now 😂, guess I need to be a little more observant next time. Thank you for your help! – user295021 Apr 2 '18 at 19:35
  • Do I have to use something like MTerminal to run Uicache? – user295021 Apr 2 '18 at 19:38
