Which Flurry library should I use for universal iPhone/iPad apps?

Flurry has a separate analytics SDK for iPad apps vs iPhone apps. If I'm building a universal app to run on the iPhone 4.0+ and iPad 3.2+ (iPad native, not compatibility mode), does anyone know which SDK/lib I should use? And is there any reason I shouldn't use the same SDK/lib for apps running on iPhone 4+ only? (Basically, I'm confused as to why there are separate SDKs at all.)
