Left corner outstanding

[Fixup]

My two Sprint Diamonds have this same problem: the left corner (above the home button) of the screen cover is raised up about 1 to 2 mm. On one of them, I can push it down, but it will go up again after a while. The other one is 2 mm up (ouch!) and I cannot push it down, it also leaks light.

I did a brief search on this forum and saw at least 3 reports for this problem.

What can we do? A $550 phone cannot be like this (don't get me started about the hard buttons).
