I have installed a 'FlipFont' application in my E63 mobile's memory card and when i restarted the phone it just flashes Nokia logo and shuts down. I think this application was some sort of virus. Now since i am not able to boot the phone so i am not able to soft format or hard format the phone. I have tried removing the memory card and restarting but that also doesn't work. Plz help me to overcome this problem.
