Wifi doesn't work after the jellybean update unless sim removed or flightmode enabled

  Hello Everyone

after upgrading to JB on my friend's Xperia S phone, WiFi does not work at all when SIM card is insreted however if i remove the sim card or enable flight mode everything works just fine.

also this problem is not only on Xperia S phone , but it occured on other phones like Sl and Acro S

I guess it has something to do with the fact that the sim is syrian

Please someone help us with this problem , Syrians want to have Jellybean on their phones but I also want to use WiFi with SIM card inserted an be able to use the phone!!!!

SONY guys please help!!!!!

Thanks in advance.
