I know this is a way too old technology but I've got some files inside a very old cellphone that I need to transfer to a very old computer.

So far my Infrared USB device works well, it's detected by the machine (lsusb output):

Bus 002 Device 002: ID 0df7:0620 Mobile Action Technology, Inc. MA-620 Infrared Adapter

I've tried to send the file over MMS and even email (it lacks bluetooth, not to mention USB). But this cellphones's firmware doesn't let me attach the files. The file was originally transfered via IrDA, and it only has an internal memory (a whole 2 million bytes! whoa!).

I found a package called irda-utils, but it seems that there are only two executables: irdaping and irdadump. I think the dump utility might do the job (which as far as I can see it's kind of a version of tcpdump but for IrDA), but I don't even know how to process the received frames.

Could this question may be what I'm looking for?

EDIT

While reading through the Linux Infrared HOWTO I found about the OpenObex project, which may be what I'm looking for...
