I have an htc 8125 phone that I bought an unlock code for. I entered the code and it worked fine but after using the phone for 5 to 10 minutes the screen goes blank then it gives me the start up screen then the windows moble screen and cycles between the two. i have to take the battery out of the phone to shut it down when this happens and the battery can have a full charge when i begin but it will be almost completely discharged when this happens. If i'm just playing around with the phone without my sim card in it this doesn't happen and I have no problems but can't use the phone or internet
