Does that phone have bluetooth and does you computer have a bluetooth port? if it does connect to your device via bluetooth and access those files, or transfer files to it. That one way to do it. If you d not have bluetooth built in you can buy a bluetooth devices for linux and connect via that. This is one way. Theres other options you can search for. Such as usb connection.
If you do have bluetooth available than you must find your distro commands for HCI for example in ubuntu 8.10 its hcitool, or hciconfig which outputs in concolse you devices that you can then access, like any other drive.
