I updated my Sony Ericsson Xperia X8 with seus and after the update i opened it.... I filled in the code for SIM and after that the phone has an icon in the top left with a SIM card and a little x next to it. Also i could see only the backgroud image of the phone and nothing else. Then i use the phone without Sim card and it worked normally. What can i do to fix this problem??? plz help!!!!
