Why were we fussing around with third-party screenshot utilities all this time? Probably because there wasn’t anyway to enable the hidden screenshot function in iPhone firmwares v1.1.3 and after.
Well, thanks to the work of RipDev, we have news that the hidden screenshot functionality is a simple matter of editing /var/mobile/Library/Preferences/com.apple.springboard.plist. Screenshots can be taken by flipping the “Mute” switch while holding down the “Home” button. We have no idea how they figured this out, but we’re thankful nonetheless.
For those of you not willing to get into the nitty gritties of editing a .plist in your iPhone’s file system, you can simply add “http://repository.ripdev.com” to your Installer.app source list (this is how you do that), and install “Apple Screenshot Enabler.”
Done, no more third-party screenshot utility mess to deal with. Enjoy.
