Sometimes when you need the most they fail. Instead of having your Iphone service in Greenhills, I think it would be better to check this listing below for a possible much better Apple Authorized Service Center. No worries and less hassle in my Experience. Best way to have your Iphone , Ipod, Ipad repaired.

If you got your Iphone at Globe. Head on to their business center. I think they shipped your unit in singapore for possible repair.
