iOS 6.1 became available on Monday, and no doubt you will want to upgrade. If you're in the habit of syncing with your desktop computer, you can simply connect your device and go into iTunes and click the Check for Update button. However, you may want to consider updating "over the air," which requires a WiFi connection. A great article on TidBITS recommeds this method of updating because the iTunes update is much larger. For example, the iPhone over-the-air update is 107 MB whereas the iTunes update is 989.5 MB.
