UMA is phone service over wifi connection.
I got escalated to RIM. They confirmed an issue that they said was affecting wifi devices though not necessarily when on wifi. They said there was nothing we could do on our end to fix it and to wait for resolution on their end. I can send mail and it seemed to go through but nothing is being received on my BB. Additionally, I have no browser access and my data apps are not getting any data either.
A few minutes ago I just got 65 emails and a bunch of BBM convos. The browser started working again, too. However, my browser is back to not working very well again. I think this is getting resolved but as is the case with all RIM outages that are resolved there is always a backlog of messages to be sent out and it can clog up the system until everything is back to normal.
