Joe Rossignol, reporting for MacRumors:

iPhones that have undergone any third-party screen repair now qualify for warranty coverage, as long as the issue being fixed does not relate to the display itself, according to an internal memo distributed by Apple today. MacRumors confirmed the memo’s authenticity with multiple sources.

This is surprising news. I never would have expected Apple to change a policy like this. But I suppose it does make logical sense. If the third-party display isn’t causing the newly found problem, it shouldn’t affect whether Apple is willing to perform the repair.
