How to Transform iTunes 10 into High Contrast ModeApple shocked millions of iTunes users by substituting low-contrast, one color icons in iTunes 10. Depending on your opinion, that change was one of the most unappealing updates made from iTunes 9 to iTunes 10. This hint will show you how to change the icon's appearance to give you a high-contrast side bar and listing pane (and, hey, change things up a bit). 1. Close iTunes 10 if it is open.2. Open the Terminal application located within the Applications/Utilities folder on your Macs hard drive.3. Enter the following command at the terminal prompt and press Return to turn on the high-contrast icons:defaults write com.apple.iTunes high-contrast-mode-enable -bool TRUE4. Launch iTunes 10 and check out the new icons. If you like them there isn't anything else you need to do, but if you don't like them go to Step 5.5. Enter the following command at the terminal prompt and press Return to go back to the low-contrast icons:defaults write com.apple.iTunes high-contrast-mode-enable -bool FALSECompatibility: Any Mac running iTunes 10.BeforeAfterBonus: Check Out Field Test Mode Returns in iOS 4.1There is a new limited version of the Field Test mode that has been reintroduced in iOS 4.1 after mysteriously disappearing in iOS 4.0. Simply launch the Phone app and dial *3001#12345#*, then press Call. Now you will see a number, representing the signal loss in dB, in the upper left side of the iPhone display.The signal bars on your iPhone will be replaced by a number. The higher the numeric portion of the negative number gets the worse your signal is. For example, -100 is worse than -79. If you tap on the displayed number the display toggles between displaying the number and the normal signal bars.The original field test mode in iOS 3.0 had a more robust set of features being reported, but signal strength is all you get in this version.Once you are done marveling over your signal strength press the Home button to exit. The signal strength bars will return momentarily.Compatibility: iPhone running iOS 4.1.Follow this article's author, David W. Martin, on Twitter.
