Transformer Prime owners in the U.S. are waking up this morning to a notification of a new OTA update that should bring improved Wi-Fi and Bluetooth performance, along with a new kernel. Since there's no official changelog just yet, little is known for sure what else this update packs, but we're hearing that it also brings a fix for the random reboot issue that plagued many users after the update to Ice Cream Sandwich last month.

As soon as more information becomes available, we'll let you know. Until then, you can see if the update is available on your device by heading into Settings > About tablet > System firmware update.
