I just updated to 4.3.2 yesterday. Since this afternoon, my phone does not have any cellular data connection, except for wi-fi. I have checked all the settings and everything is correct. I have even tried to restore the settings and restore the phone. But it still stays the same. Does anyone have the similar problem before? Could this be the hardware problem? No "3G" or "E" or "o" icons anymore. This is singaporean network btw. Appreciate if anyone can help. Thanks.
