Hi, All. Likely a naive question (sorry). Today I opened plants vs. zombies 2 on an iPhone running iOS 8, and the application downloaded and installed a patch. Is this act kosher? I wasn't aware that applications could update without the app store. Likely I'm just paranoid because of all the masque attack news, but just wanted to check on whether an app downloading and installing a patch outside the app store was a normal occurrence. Thanks so much for your help.
