Apple's 'Find My iPhone' Web Maps for iCloud.com Beta Move from Google to Apple
Apple has been slowly switching away from Google Maps after using the competing mapping service in the early versions of the iOS. The Cupertino company dropped support for the Google-based mapping solution and introduced Apple Maps as part of iOS 6 in 2012. While iCloud.com still remained tied to Google, iOS apps such as Find My iPhone and Find My Friends also were converted to Apple's mapping data in the same year.
After a highly-criticized launch, Apple has been making efforts to bolster its mapping data, recently improving its points of interest database as well as notifying users when reported problems had been fixed. Apple was said to be adding indoor mapping and other new features to Apple Maps in iOS 8, but internal politics and the departure of key employees may have delayed those plans.
Update 10:22 AM: Some users have been seeing the Find My iPhone web app on beta.icloud.com switching back to Google-based maps, so it appears that Apple is continuing to tweak and test things.
