    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.

    Are your APN entries correct, or your carrier file installed?
    Settings > General > About - what is the value for "Carrier"?

    Might be worth a reset of your network settings.
    Settings > General > Reset > Reset Network Settings
    This will also wipe all stored WiFi entries and their passwords and reboot the phone.

    Carrier is Starhub 10.0. The phone was perfectly working before. I've never jailbroke this phone before. I'm still under contract with Starhub.

    I've tried to reset the network setting already. Also reset the phone as well. Nothing is working. :(
