Thanks for your suggestion , Turboladdade.

Mine is not jailbreak. App Store problem is not me only ( also not Singapore only) . I have seen at Apple web community ,a lot of people got the same problem like me from all over the world. May be Apple server problem!

I have tried restart , reset setting and also restore from iTunes . But I still couldn't access categories

I am using 3G iPhone. I couldn't access Categories in App Store , but all the rest Featured , Top25, Search,Updated are Ok. Colud some one help me ? I have no idea.
