Apple has released iOS 4.3.3, which alters how iPhone and 3G iPad devices store and back up a built-in location database cache.
Apple faced criticism last month when two data researchers publicly announced their discovery of a location database cache stored on the iPhone and backed up to Macs and PCs using iTunes. Apple answered the questions and concerns of politicians and consumers last week.
The iOS 4.3.3 update is part of the company's response. As the release notes point out, this update contains changes to the iOS crowd-sourced location database cache, including:
Reducing the size of the cache
No longer backing the cache up to iTunes
Deleting the cache entirely when Location Services is turned off
