If it's a Verizon Razor then you won't be able to do it. Verizon disabled OBEX (e.g. file transfers) on their phones in the firmware. It's been hacked with firmware from other providers, but that was a while back and the newer revisions of the phone won't work with the hacked firmware.
If you're losing the connection, then try plugging your phone in when you do the transfer.
