Hi, i'm very new to this. I actually was just concerned about my phone because i'm not knowlegeable about its function. I just bought the samsung vibrant off ebay, and details stated that it worked 100%. When i received the phone, with only a USB cord, I've tried to mount it to my computer and it will not charge at all. It, actually, shuts off once it's mounted. I'm looking for someone that might be able to fix it if in case I won't be able to send the phone back. Please help!
