Apple to Cease Accepting Apps that Access UDIDs
Mar 22, 2013, 7:33 AM by Eric M. Zeman
Apple recently indicated via its developer portal that it will no longer accept new apps or app updates that access UDIDs. The UDID (unique device identifier) is a code that refers to each iOS device and can be tied back to the owner's identity. The UDID was originally accessed by advertisers in their apps, but Apple began restricting access to UDIDs in 2011. It replaced the functionality of the UDID with anonymous Vendor and Advertising identifiers when it introduced iOS 6 in 2012. Beginning May 1, any app that attempts to access UDIDs won't be allowed. The measure is being taken to improve the privacy of iOS device owners. Apple is also mandating that all apps submitted to the App Store support Retina Displays, and the iPhone 5's 4-inch display. Apps not optimized for the iPhone 5's display float in the middle of the screen with black bars above and below the app. This policy change also goes into effect May 1.
