Apple replaces ‘Airplane Mode’ prompt in iPhone OS 4

Apple has replaced its prior “This accessory is not made to work with iPhone” prompt with a slightly more descriptive alert in the latest beta version of iPhone OS 4 for the iPhone and iPod touch. The prior prompt asked users if they would like to turn on Airplane Mode to reduce audio interference, noting that they wouldn’t be able to make or receive calls and giving them yes or no options at the bottom. In contrast, the new alert in OS 4 says “This accessory is not optimized for this iPhone,” noting that “[y]ou may experience noise caused by cellular interference and a decrease in cellular signal strength,” with no mention of Airplane Mode and a single “Dismiss” button at the bottom.
