Apple is beginning the transition to move its Maps application online starting with the Find My iPhone web app on its iCloud.com beta website, as noticed by iPhoneBlog.de [Google Translate]. Though the public version of iCloud.com is still pulling data from Google Maps, beta.icloud.com now uses an online version of Apple maps for its location information.
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.
