Joe Belfiore has tweeted that LockScreen app, which was promised with Windows Phone 8.1 release is almost here. The Beta version may be released in a week’s time. Joe had promised arrival of LockScreen Beta in couple of weeks, back in June.
The delay apparently is due to some snags and addition of a new feature. As per the tweet, the Beta release will support only English language and will be available for devices with 1 GB RAM.
