if he dont know wthat is pr 1.2 you guys should stop to tell him to overclock. first overclock is just something for guys that know what to do,you will loose your warranty and maybe your phone will be laggy and "bricked"so you will have to flash it. but if you dont know what pr.1.2 is i guess you dont know what flashing is. pr.1.2 is the actual firmware. go to the program manager and install all updates then reboot and maybe your problem will be solved. and i recommend to you> DONT LISTEN TO THE GUYS HERE AND DO NOT OVERCLOCK YOUR PHONE!!!!!! if you have learned something about your phone,voltages,batteries,mhz, if you now how to flash and if you dont give a **** about your warranty you can try it
