I have a Sony Ericsson Xperia X10, and I updated the software to Gingerbread (Android 2.3.3), but I'm having problem connecting my mobile to 3G provided by my Network. When I go to settings and search for the networks available, it shows that I'm already registered on the network.
Though I have the data access via mobile network enabled, and WCDMA Network Mode, the mobile network state appears Disconnected!
