I have a USB for my Samsung SCH-U410 it also has bluetooth.i bought the cable from eBay and was expecting a driver 2 be installed or my computer had software already for it but it didn't and does nothing when I plug it in. It is CDMA phone and I am with koodo. I have 230 contacts that NEED to be backed up in case i lose my phone, i dropped it in water once and I was so scared it would be dead but it isnt but I am getting scared now because I have dropped it more and more these days. Anyone know how I can back my contacts up? Not onto just a sheet of paper but also a file or something I can install onto phones with SIM cards or other CDMA phones. I used to be able to back up my SIM card when I was with Rogers, but CDMA sucks!
