My sister's phone is brand new from United Mobile and it keeps crashing. A blank white screen shows and then the phone won't even restart. We've got to take the battery out and more or less pray it works when we put it back in.
She's not got GPRS or MMS (how do we activate it? Ufone says it's on..) and not much has been added to the phone, since it's only 1 or 2 days old. Why does it crash and how can it be fixed?
