Discoloration Caused by Cases, Not by Overheating

Last week, we found reports that the iPhone 3GS had overheating problems, particularly the white 16GB version. Those overheating issues sometimes lead to discolored white iPhones. Hardmac followed up with the FrenchiPhone editor that reported the problem and reported this:
-According to discussion between FrenchiPhone editor and Apple
Support, the red strips are not linked to a potential overheating of
the iPhone 3GS, but rather to a chemical reaction due to a component
found in some protection enclosure originally sold to preserve the
precious device! Indeed, they could show that a small label sticked on
the enclosure prevented the corresponding area on the backside of the
iPhone to turn red.
- One solution to get the iPhone 3GS white back is to clean the
backside with alcohol (they tested it successfully), and it perfectly
work.
It looks like the mystery has been solved. We should all celebrate with some delicious Scooby snacks and return to solving the mystery of the haunted fair grounds. Hardmac wants to remind you that if you do have to clean your iPhone, use ethanol/alcohol and not acetone.
