I was searching the Blackberry App store today on my Blackberry and came across an app called BB Scanner that is a bit like liveatc.net but for fire/police/emergency.
Anyway, I installed it and entered in the URL for my feed and it worked
I did a search on the forum here and couldn't find a reference to it, so I thought I'd drop a note to everyone.
At least now I can check that my feed is working when I'm away from home.
