Which one do you use and why? I'm in the droid world and I'm currently using Score mobile. I like that you can easily switch between sports and that you can also "track" the game and have different kinds of updates sent to you regarding the teams that you select.
I use Yahoo's Sportacular for updates on scores. Simple...easy to use. I like it. Runnign on HTC Rezound. Had a friend tell me about Thuuz. Have not tried it yet, but it looks interesting if you want to be alerted about a good game you might be missing.
i use Sportacular mostly. Also use Sportstap . about the same features as Sportacular. I rate them as good, not great.
