My mom has a Samsung Gleam and she does not like any of the ringtones that came with the phone (she says they are all too loud and sound like everyone elses)

. I made her a couple of mellower ones at home, but I am unable to transfer the .wav files via bluetooth or SD card (the gleam stops the transfers and does not even recognize my SD card). Any advice on how I can transfer the files to my mom's phone? I would like to avoid reformatting my SD card if I can since it works fine in my Samsung Sync.
Thanks in advance for any help!!!!
Sam
