I just hit thanks! Ive had the same issues as above with losing contacts, exchange data, messages, etc. Thankfully, i had a recent backup file. Some programs didnt work and wouldnt fully uninstall (Google maps, sprint nav) so i deleted the "program files" folders in file explorer and was able to re-install. {hope that helps}

hopefully it doesnt happen again before the next release comes out.
