A little update to the native Evernote app for BlackBerry 10 is currently rolling out through BlackBerry World. The update itself brings the app into v5.2.1.394 and though it doesn't have any huge changes in it, it does address problems with one important feature and that is a bug the prevented customers from purchasing premium accounts. If you're an Evernote user, best to grab it either way as there may be some other undocumented changes as well.
