Please help iOS5 users!!!

Okay, so you updated it. And I have ipad 1 and it wont take iOS 6.
So now my Apps icon is stuck with a little "1" in the corner. Can you fix this please? Other App developers manage to do it when they abandon users who have older iOS.
If I have to delete it then please give me my $2 back.
And yeah, its a great app. :-)
