While I would write "iPhone" correctly, I have no patience for names with gratuitous punctuation in them, e.g. "Yahoo!". In a sentence, I would write "Yahoo doesn't want to be acquired by Microsoft", not "Yahoo! doesn't want to be acquired by Microsoft". Keeps things easier to read, don't you think.

AT adds: AT doesn't actually have anything to add.

AT really adds: Oh yeah?

"AT adds: May I suggest you learn English?"

Lol inq.... You fail at English.

nine months after the official launch you still cannot spell iPhone correctly: may I recommend methylphenidate?

AT adds: May I suggest you learn English? The Inq's policy is to ignore stupid marketing spellings with capital letters in the middle of words and to treat them as proper names with an upper case first letter. We also take a perverse delight in annoying people who send us press releases saying things like "Please note, VIA should always be ALLCAPS".
This is why we refer to Via (ALLCAPS)
