I have no USB cable for my phone so i put my memory card in a phone with a USB cable (Samsung D900i) but the screen is smashed. When i plug the phone into the pc i can't get into the folders, is there somthing i have to click on the phone to allow a USB conncection?
Every phone I've ever seen needs software in the PC to transfer anything from it. Sometimes it's quite expensive for what it is, too.
If you're trying to transfer video clips, some phones use odd formats that standard windows programs can't handle. Stills are not normally a problem - so a card reader may be a good idea. Make sure you ask so that you get one that will definitely handle the type and capacity of card you have.
