When I switch my phone on, the sony ericsson logo comes on then after a couple of minutes please wait comes up on screen and its stuck on it until i take the battery out. This happens everytime i switch the phone on. I dont know whats going on. I dont know how to format/master reset it either. I have tried updating on the sony ericsson support site but thats not worked either. Does anyone have a solution to this problem? I would really appreciate it thanks.
