Lighting in unity 1.5

it seems my lights have gone haywire in a file that was in unity iphone and opened in unity iphone 1.5
has anyone had the same problem? everything is too bright. maybe there is a new default lighting that i need to disable?
tx!
cp

Is the iPhone 3G emulation enabled?

Also keep in mind that some materials were ported to the iphone, they not needfully use the “bottom end desktop fallback” any longer
