I made a thread about this problem 2 days after iday of Getting the iPad 2 on another forum that thread was big but people with black seemed to not have as much light leakage.
I'm using a bodyguardz full body clear protector and it's cut perfectly nice and really clear I see no image quality lost and little to no orange peel.
I use text free from the apple store on my ipad2. Its awesome let's you send picture messages aswell even call someone using wifi in the app it's awesome.
