iScore running on iPad 2 now wanting to run on new iPhone 4s

[Scott1719]

I have been using the iScore Baseball on my iPad for the last 2 - 3 years without any issues. My carrier Sprint with in the last 6 months or so finally got the iPhone. I see that this app runs on iPhone as well, but the only way I can get it on my iPhone is if I buy it again. Why can't I bring this app on my iPhone 4s without buying again? I use the the same iTunes account for both iPhone and iPad 2. When I view in iTunes the Apps tab it show ESPN iScore for Baseball as a iPad only app. I would assume that is why I can install on my iPhone. Is there 2 different apps of iScore, one for iPad and one for iPhone? or should i be able to install on my iPhone like so many other apps?

Thanks!

There are two separate version of iScore just like so many other apps (Angry Birds vs Angry Birds HD for example). The iPhone version will run on the iPad, but will just run in 2x compatibility mode and does not take advantage of the full screen of the iPad. The iPad version only runs on the iPad, not the iPhone or iPod Touch.
