Apple has posted iOS 4.3.3 for GSM-based iPhones and iOS 4.2.8 for CDMA-based iPhones. The main focus of the updates is to address the location data logging brouhaha that has dogged Apple for the past few weeks.
The 4.3.3 update — compatible with the iPhone 3GS and iPhone 4, third and fourth generation iPod touch, and the iPad and iPad 2 — reduces the size of the location data cache, no longer backs up the cache when syncing with iTunes, and deletes the location cache from users iPhones when Location Services is disabled. Apple has said the tendency of iOS devices to continue updating Wi-Fi and cell tower data from Apple’s crowd-sourced database even with Location Services was a bug in previous versions of iOS.
To install iOS 4.3.3 connect your iOS device to your Mac or Windows system, computer. Choose your iPhone, iPad or iPod touch device from the Library list in iTunes, click Summary, then click Check for Update.
