White iPhone discoloration: Not just heat
Last week, several readers were pointing out stories of white iPhones that had taken on a yellowish hue. It was assumed that heat was the issue. Keen to tempt fate, I played Star Defense [App Store link] for 30 minutes straight last night with my iPhone resting on my bed. It warmed up pretty good, but stayed white. Earlier today, frenchiPhone.com reported that the issue is most likely the combination of a hot iPhone and a certain case, though they did not specify which one. Additionally, they state that cleaning the effected area with a cloth and some rubbing alcohol will remove the stain. We haven't tried this, so we can't confirm that it works/won't damage your phone.
Our best advice, based on the limited information we have, is to remove your white iPhone from its case if you're going to be doing someting intensive for a long time, like play StarDefense, run a GPS app, etc.
I probably don't have to tell you this, but just in case ... do not apply stain stick to your iPhone.

The person at the apple store said that the white back was made of ivory, and as with all ivory it discolors over time.

A few weeks isn't really 'over time'

Ivory?? Yea, I can really see Apple slaughtering a protected species to use their tusks for the iPhone.
Look up...gullible is on the ceiling.

How about you clean your gruddy/dirty hands once in a while. I'm sure the phone is not made out of non-porous plastic, so the grime will get in the pores of the plastic eventually!

"Additionally, they state that cleaning the effected area with a cloth and some rubbing alcohol will remove the stain."
Not to be a grammar whore but the word is AFFECTED with an a. Keep in mind that affected is usually the adjective/verb whereas effect is a noun (such as special effects).
Carry on.

The fact that the device gets hot enough to cause another object to stain it is still a massive concern. Surely just as dangerous as the flaming MagSafes.

Correct me if I'm wrong (well, duh, of course people will) but doesn't alcohol actually MELT plastic? It's like Frank Drebin says about drinking Draino: "Yeah, it'll clean you out, but it leaves you empty inside."

You're thinking of paint thinner. Low concentration rubbing alcohol (isopropyl) will not damage your iPhone.

Alcohol can damage some types of acrylic, but most consumer plastics are ok (PE, PTFE)

A Mr. Clean magic eraser should do the trick. It's always helped clean white plastic for me. #xbox360

If it is anything like the blasted white keyboards, users LOVE typing right after eating Cheetohs. I can only imagine the disgusting things that a phone would pick up on it.

I have a 32GB White that I use enough to just about drain it flat every day. It lives in a "Power Support Air Jacket for iPhone 3G" that I got from the Apple online store and have had zero problems, except for unreliable Bluetooth that appears to be effecting 3.0 OS devices.

iPhone 3GS Turning Red: A Problem with Some Protection Enclosure?
Last week we were reporting about cases of iPhone 3GS white having part of their backside turning red after being extensively used, indicating a potential damage linked to overheating.
However, we have received additional details that could provide a good explanation to the relatively low number of reported reddish iPhone 3GS:
- 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.
So, this should mark the end of this one week-long story. Do not use acetone instead of ethanol/alcohol.

I don't know what type of plastic Apple is using but I would not be surprised if they used some blend of polycarbonate. If, in fact, it is polycarbonate I would be cautious in using alcohol to clean as isopropyl alcohol can accelerate stress cracking - try to get a commitment from Apple Technical Support that it is OK before proceeding. That way if it does start to crack and craze Apple will be on the hook. If they won't commit to a cleaning method, the weaker the alcohol and shortest duration the better.
