Hi,
I want to put MP3s on my LG Rumor and get pics and videos off it.

I don't have a connector cable for it, or a MicroSD reader.

I do have a Nokia 770 (without an RC-MMC expander card) which I can connect to my computer via USB.

Both the 770 and the Rumor have bluetooth, so I thought maybe I could use the 770 as a sort of modem to put MP3's on the Rumor and get pics and videos off.

How exactly would I do this? Has anyone out there done this before? Much thanks.

You can set up ad-hoc network (local network)
linking Nokia 770 with laptop over wifi or bluetooth
and have mmc1 catalog/directory of your tablet visible as a drive on your laptop.
To copy files you can just move them to mmc1 drive, like copying files to a pen drive.
