I got a new original iPad Thursday from my local Verizon store. I love it, but yesterday I was putting on a Yoobao slim case and noticed that if I press on the glass near the top right side, inside the black border, it flexes and squeaks. This spot on the screen has a bit of backlight bleed (not terrible, but still there) if that has anything to do with it. The glass apparently touches the screen underneath as the "rainbow" type effect happens -the same effect seen when you touch an LCD. The pressure required to replicate this isn't extreme either, just a medium firm press. Should I be concerned? I'd hate for this to turn into an issue down the road. Thanks for the advice.
