Hmm, that last part about SMS Backup/Restore only working if you're the default SMS app seems a bit annoying.<p>The workaround they suggest - setting yourself as the default SMS app, then unsetting it - seems a bit hacky. I suppose you'll also need to handle the case where a SMS arrives whilst you are doing a restore/backup, and your app is set as the default SMS app.<p>I wonder if this is a permanent thing from Google, or if it's just a temporary thing until there's a proper SMS backup/restore permission.
