You can pretty much do that for the Bulls anyway without the need for any special apps.
If you sign up for a twitter account (assuming you don't already have one) and follow the Bulls tweets, you can set them to text to your mobile. Every time the Bulls put a news item on their website, it always goes to twitter straight away and then it texts the headline to your mobile (as well as a link if you have web capability on there).
Means you pretty much get a text as soon as the Bulls put any news item on their site.
