According to them, no directive was given to them from Maxis to give 500MB x 12 mths.

And guys, if i had more sense, i'd forget about looking for the iPhone 4 from Maxis, especially today (17/10) and tomorrow (18/10). I believe that Maxis are keeping as many stocks as they could for the upcoming Maxis roadshow, spanning from 19 - 31 Oct at several places.
Refer to the schedule at http://maxis.com.my/personal/iphone4/landing.asp for more info.

And as for Machines stocks, i have a very strong feeling that they won't be receiving anytime soon. Especially KLCC branch, as they will be co-joining with Maxis in the said event.
