The full RUU for upcoming Thunderbolt OTA update has been released thanks to Jcase/TeamAndIRC and Android Police. This is a Froyo release, hopefully the last one. This is for non-rooted users and will wipe all of your data. It is highly recommended that you do not flash over a rooted phone. Hold out for Jcase to release the rooted version soon. I have it available to download off my http server below and you can see the original sources below. Didn't see anyone start a thread for this yet.
