Can i use card reader instead of connecting my phone to PC. wat r the functions of card reader. do i need any software to transfer files from my PC to Memory card?
Often times you don't. Once the card reader is in the computer, the computer sees the memory card as another drive. All you have to do is copy the file from PC and paste it into the memroy card reader drive. Just make sure the file your transfering is in a format that the phone understands. ie. .wav , .mov, or .mpg.
You can use card reader to fill memory card with movies, music and such files but you cannot install software or games over card reader. I suggest you describe your problem with PC suite here and you will find your answer in no time
