So, did the upgrade to 4.3 and all seems to work fine other than I get a perpetual notification about a PDF I downloaded several months ago. I clear the notification but it comes back in 30 mins or so. I open the PDF and delete it, but it still comes back with the download notification. Annoying. I don't know if it is actually downloading the file each time, I think it just tells me it is downloaded, but who knows. I would call US Cellular, but their wait times are a joke right now. My wife waited 3 hours plus yesterday, and still no answer. That was on a call back too! Anyway, any suggestions?
