Hm, strange that someone told you to call ATT... I don't know what was in the update, usually after the update completes "successfully" it will give you a small description of what was done, they usually tell you nothing exciting. As an example mine always says they fixed android wireless, yet my phone still randomly will disconnect. It will probably prompt you again next time you drive it, I don't recall mine ever saying please leave the engine running for the update, If I recall it says don't drive it during the update? But they aren't quick, usually takes about 20 minutes, I'll pull up someplace after a drive turn the truck off and it will tell me there is an update, I hit continue and walk away, when I get back in later it's all done and ready to go. My guess is it will resolve itself either in a day or two, or next patch, I had one fail to install, and the next release it installed. Hope that helps a little maybe...
