Just to clarify this one for everyone who's equally puzzled like I was: In the package description in Cydia it is explained quite detailed but long story short:
Anyone EXCEPT old-bootrom 3GS users with any untethered jailbroken 5.0.1 device, no matter what way you have put the JB on your device (Absinthe, Cydia-Corona-Package, CLI, etc., they all deliver the same underlying corona exploit just by different means) can and should (over-)install this one on their devices. And to save you from reading, yes, even if Cydia shows the package as not yet installed!
Nuff said.
Best, CV
EDIT: Just saw Betabots comment (Too fast for me ;-) ) and by my own experience I can verify it works on the iPad2 as well... and from this post of Saurik himself on Twitter: Quote: "Corona 1.0-8: @sbingner noticed that 1.0-6/7 failed on iPhone 4S 5.0 (the only supported 5.0 build; absinthe's Corona had worked): fixed.

" it's clear that it is intended for the 4S as well...
