ringtones on phone w/o a usb chord

I have a micro usb card, but no usb card for my phone to plug it in to the computer, is there still a way for me to put my own ringtones on the phone through my microUSB card?

my laptop actually does have bluetooth, so i dont have to send my self a picture message to get the ringtone? if that is the case, how?

You can't actually get ringtones off of the microSD card. They need to be on the phones internal memory. In order to get a ringtone, you need to use Bitpim, or send yourself the sound using various websites.
ex: phonezoo
     myxer
You can save the sound directly to your My Ringtones, or save to my sounds.
If you save it to my sounds, you need to send that sound to yourself via text message and save it to My Ringtones.
If you have a sound on your microSD card, you can always send it to yourself and save it as a ringtone.

With another phone I had, Bitpim did not detect the phone while connected with bluetooth.
But that doesn't mean its not connected.
Try to get phone data.
