technically there is no such thing as inside information...
by definition inside information gives someone an unfair advantage which is illegal by the SEC.
like you said, anyone with any insider information is considered a 'market maker'...a big dog in the market. i can probably safely say that no one here has anything that we would consider inside information.
aapl stock will do one of two things based on the iPhone, and it will do it to a great degree. it will either skyrocket to 130-140-150 or it will drop back down to 100.
if the iPhone is a success on release (on time "late june release, lines around the block, positive user critiques, etc. etc.) then the stock will shoot up quickly. if there is any sort of bad news re: the iPhone (DELAY, no demand, bad reviews) then the stock will plummet.
Apple stock, at this point, is moving up and down on rumor alone...and it's moving a lot. when engadget reported that false delay, the stock lost $2.5 BILLION in market cap in 20 minutes. that was a rumor...imagine what would happen if it was actually true. when steve jobs appeared at All Things D earlier in the week and gave VERY vague information re: the iPhone the stock shot up 2,3,4 dollars. imagine what will happen when concrete information like release date, and sales #'s come out!
with that said, i think it's safe to say that the stock will go up, iPhone will be a success, and if you stay long on your investment you will make a nice little profit.
