hi guys, i'm not sure what's happening, but whenever i turn on my packet data, it's not working, i saw the H and 3G logo, it's uploading, but it's not downloading, anyone know what's the problem? i'm using maxis btw.

i resetted the apn settings and it's still the same. I'm still on rooted stock 2.3.5, this is the first time i use 3G on this phone. The thing is, after i turn on packet data, the 3G and H logo, will keep switching between itself, and it's only uploading, not downloading.
