SingTel sent out an email requesting those who has registered their interest in Apple iPhone 5 to proceed to the website to book an appointment. The location is at Marina Bay Sands Exhibition Hall D from 21st September 2012. It did state that it will not be able to share the pricing.
So, if you are one of the registrants and wanted to be the first in the world to get iPhone 5, check your email now. I do not know if other Telcos are doing the same now but if you know, do let me know, ok?
