Just a day ago Apple released the newest version of iTunes to all its customers. iTunes 10.3 beta brought a few very interesting new features to the bundle, including the first beta features of iTunes in the Cloud.
Apple just released an update for iTunes and released version 10.3.1. You can grab the new update either on the Apple website or fire up Software Update to download and install it.
The update description Apple provides for the update states absolutely nothing about what’s been changed or fixed in iTunes 10.3.1, but lists all the new features of 10.3.
After reports of users having problems syncing their iOS devices with iTunes after updating to 10.3 (iTunes would give out an “unknown error (-50)” message) , it is only reasonable to assume that Apple quickly fixed that bug with the update.
