Quick post to recommend Badmania98's service. I did a session with him and now my notifications are working again. There are a few apps that didn't work, but for those there are workarounds. Price is very reasonable too. I'm on the latest firmware (186 I think) and did not have to start over or delete any apps. Badmania98 was very kind and helpful and it's wonderful not having to open apps to check for new messages anymore.
