Mine is successful 

I also got another email from ceo's office (can't mention the name here) stating that someone from the iphone 6 team will call me in advance before the site is open to the public to take my order details as im their exclusive privilleged customer.

I forsee that the site will only be available for booking to the public by 12 noon I guess..

i have call 123...

those who receive congratulations mostly are new maxis customer or do not held any phone contract with maxis...

those who got failure message like me, are those existing customer with got any phone contract with maxis...
hence, they already got lots of complaint regarding this issue and they are fixing it right now and 'they maxis' claim we 'might' receive a new email anytime soon........
those message above are from maxis operator.....

BTW, my friend's sister called to Maxis center. They said the email was a hoax. They said someone has hacked maxis server to send those email. wonder how true it is..hmm
