Just 6 days after releasing iTunes 10.2, another update is available today. iTunes 10.2.1 doesn’t seem to bring anything new to the table. Just like for iTunes 10.2, the changelog only mentions this new version of iTunes is needed to sync your device with iOS 4.3.
Additionally, and like the previous version, iTunes 10.2.1 brings improvement to Home Sharing. In short, this release is probably about small bug fixes…
I was able to sync my jailbroken iPhone without any issue after installing iTunes 10.2.1.
Let us know if you find anything new in this version of iTunes.
