Just back from customer service centre berjaya plaza yesterday evening. They wanna charge RM100 coz mine is AP, not ori from samsung. But, after 10 minutes, they finish the job with an error:can't connect to 3g. They said, maybe the hardware problem, need to send to the essembler factory, then they said sorry and give back the phone.

Haha..actually just add APN, then the 3g function come out.
