2 weeks ago, i went to replace my maxis iphone due to the home button..they have a policy whereby they replace the whole unit and not fix the home button only..
only maxis centre at klcc and ttdi have the service, other centre will have to send it back to either of that 2 centre to get the replacement.
so if u dont want to be seperated frm ur phone for more than 2 weeks, go there cos only being phone-less for 30mins max..
they will give u a new unit and a new service card with the phone..
