I am an avid hockey fan, and I want to get the nhl gamecenter app when I get my iPad. I have the nhl gamecenter app for my iphone, but that app is only good for stats, scores, etc. I want to get the live version, so I can access the live feeds for out of market games. I have a few questions in regard to the iPad version of the app: Before I upgrade to the live version, do I need to download the premium app or can I upgrade from the free app? If I purchase a subscription for the service, can I use it on my computer as well as my iPad? How is the quality of the live feeds and other features that come with the service on the iPad? Thanks in advance for the help.
