“…Oscar I can’t hold her; she’s breaking up!…” – Not Steve Austin’s aircraft as in the Six Million Dollar Man this time;

rather it’s the Apple iPhone 3G.

A number of people have noticed cracks appearing in the casing of their (IMO waste-of-money) iPhones.

Seemingly only in the white ones.

All people who have reported this claim have only subjected their (cr)Apple iPhone to normal use without any abuse. The damage is mainly hairline cracks appearing in various places; but just like an eggshell if these get long enough and plentiful the case will come off, and the wheels might come off Apple as a result.

Hey Steve Jobs: ‘See where greed gets you? : Rush rush rush – Crash! Bzzzzzzzt: Fail!   http://kkomp.com/archives/203

Apple has replaced a few phones; but staff will probably start to refuse, as numbers of returns swell, on the grounds that the damage is only cosmetic: That will lead to many pissed-off customers, loss of cred for Apple, and many of these heaps ending up where they should IMO have been put in the first place, namely the dustbin. Apple rely on the cosmetic appearance of their product to distinguish it from the competition.

Once again though, it hasn’t taken long to crack it! Now do you wish you’d invested in an LG Viewty?

Addendum 31.07.08 :-

Today I’m seeing reports of black iPhones cracking also:

“I have been searching online because my 3G will be here in a few days, and i found that there are also people with the black 3g that have had cracking, but its alot harder to see on the phone.”

“this concerns me as well as what kind of durability does the phone have incase i drop it?”

It appears that all the Apple iPhones are easy to crack.
