Sony Ericson Arc S WCDMA doesn't work after update

When i update my SE Arc S via original sony SW (Update_Service_Setup-   also Sony PC companion)  i have a problem with internet. first problem was, that mobile can't receive internet settings. So i create APN using my mobile operator instrucion. Than internet connection works ok. But when i using internet i can't receive or create voice calls and i have set my network to WCDMA. Now i have to use only GSM, because it works (internet is down when you call ), but it is slow connection also i can't use internet during call or receive any call during using internet. 

Also after update my mobile is still in Android version 2.3.4 but Sony PC companion wrote that i have Android 4.0.

Plese help me

Re: Sony Ericson Arc S WCDMA doesn't work after update

This problem is most likely due to network. You need to have two or more networks available to be able to surf and call at the same time. Contact your network operator to check available networks in your area and also make sure that you're phone is set to use both GSM and WCDMA.
