A forum poster claiming inside knowledge has explained the discolored displays on iPhone 4s as being a result of the devices being fresh out of the factory. The bonding agent (which the poster says he was involved in pitching to Apple) between the layers of glass hasn’t had time to dry yet, he says, and normal use for a couple days should clear it right up.
Obviously this solution takes time, and we’ll only know that it worked if reports start rolling in that the blotches are spontaneously disappearing. If you have a discolored iPhone screen, keep a close eye on it and let us know if anything changes.
