A Winterboard update has been posted to cydia that resolves this issue.
Since yesterday, I’ve been overwhelmed by emails from users mentioning that when they activate Typophone Weather on the lockscreen or Clockbuilder, they lose the ability to see any notifications on the lockscreen. These include but are not limited to: missed calls, emails, text messages, and push notifications.
I can no confidently say that this is an issue with winterboard itself and not Clockbuilder or Typophone Weather, specifically. The problem is with HTML lockscreen themes, which is what CB and TW are. I’ve sent a few messages to Saurik (Jay Freeman), the developer of Winterboard to see if he has time to take a look and attempt to fix. Unfortunately, I’m sure he’s currently overwhelmed with the incredibly high demand on Cydia servers and services so it may take some time.
I appreciate everyone’s patience. If I have any spare time, I’m going to try to take a look at the source of Winterboard (it’s open source and available on Saurik’s Git Repo if anyone else want to try as well).
