Yesterday, we reported a TV cable broadcast on a possible iPhone release date. CNBC’s “On the Money” were pretty sure iPhone will be available on June 20th and even had bold letters flashing below the screen confirming the release date. Bloggers, of course, knew better and responded unenthusiastically, so unenthusiasticaly that if MacRumors didn’t have the report and a link of the broadcast on their forums, it was very likely that the entire tech blogging world would have passed over the report entirely. AAPL stocks responded again, adding $1.83 on Friday. Obviously, this is a more conservative movement compared to the big hulla balloo courtesy of Engadget two weeks ago. So the stock market is learning about iPhone rumors. This time, even with a big-time broadcast media channel backing the rumor, traders were more cautious.

Mar Siegel, a spokesman for AT&T didn’t confirm the June 20th iPhone release date when he was interviewed by AP a day later. What he could confirm was that the iPhone was on track. Apple spokeswoman Natalie Kerris gave more details: “We have said consistently that we’re looking forward to shipping the iPhone in late June and that has not changed.”

Now, I’m wondering. Isn’t the official information that the iPhone is going to be released any time next month enough news for investors to decide on what to do with their Apple stocks or whether they are going to be in a buying mood next Monday? Does it make any significant difference whether it is June 20, 15, 11 or even 30? There’s a big difference betweenquickly  reacting at relevant news and willing something to happen by buying or selling Apple stocks.
