Security fixes combined with battery, iPod patches
Apple's promised short-term iOS security update is known as iOS 4.3.3, and should arrive in two weeks or less, a source with the company says. The person notes that as expected, it should reduce the size of the location cache, and prevent the file from being backed up to iTunes. The cache should be deleted entirely when Location Services are off.
The source adds that v4.3.3 will also make some battery life improvements, and an unspecified collection of bugfixes for iPod touches. Battery drain has been a recurring problem with iOS updates, potentially showing up after previously trouble-free firmware releases. The issue is frequently blamed on runaway processes consuming power when they aren't needed.
Unmentioned by the source is the "major" iOS update which Apple says will do on-device encryption of the location cache. If that upgrade is actually iOS 5, it could arrive as late as September. Apple could however potentially distribute an iOS 4.4 or 4.5 several months earlier.
