Twenty Ways

If you have a jailbroken iPhone and find yourself unable to set the passcode lock, you can still activate this feature manually:

• set your passcode on the iPhone under Settings / General / Passcode Lock
  (this stores the passcode, despite the feature not being activated)
• open /private/var/mobile/Library/Preferences/com.apple.springboard.plist on your phone;
  the easiest way is to copy the file locally via SFTP, then edit it in the Property List Editor bundled with Xcode
• add the following key under Root:
  • key = PasswordProtected
  • type = Number
  • value = 1
• restart SpringBoard (relaunch the process, or just restart your phone)

You can also reverse this process if you find yourself unable to access said iPhone.

A recent upgrade to my iPhone left the phone unable to access visual voicemail.  When I pushed the Voicemail button from the Phone screen, the phone simply did nothing.

Caveat: In addition to resetting your password, this will also delete your personal greeting.  It shouldn’t affect existing messages, though this assumption is untested.

The solution:

• disable WiFi from the Settings menu
  (visual voicemail needs to reset over EDGE or UMTS/3G)
• call AT&T at 611
• press 1 to confirm your number
• press 3 for voicemail help
• press 3 to reset your password
• hang up and wait for a confirmation text message

The Voicemail screen should work again.  Don’t forget to re-enable WiFi once you complete your voicemail setup.

Recently I installed Debian on a DEC Multia, I documented this install on my own blog. During my long upgrade process to a current Debian release from Woody. I encountered the following error:

midget# dhclient

Unrecognized Kernel Version

The way to fix this is to edit /sbin/dhclient and locate the line that contains “2.[12345].*)” and change it to “2.[123456].*)”
