A friend in my office just got a 3 mobile branded Wildfire. and he is having a problem. Sometimes when the phone rings he is completely unable to answer it all the controls are frozen and there is no way to answer or even reject the call. This is very annoying especially in the office. I has happened twice and he has had to pull the battery to stop it happening. Both times it has happened it is when he has a previous missed call but not sure whether this definitely a factor or not. Anyone else had this problem and know of a solution?
