I've recently bought a Sony-Ericsson K300i mobile from Tesco on "their" network (actually O2). A superb little phone at effectively £40 (discounted when you buy £20 of airtime at the same time, so you have to dish out £60).

It works very well with my desktop PC and a cheap Sigmatel based USB-to-irda dongle. (vendor/product 066f/4200 module is stir4200)and obexftp, some examples of commands are:-

To 'get' a file:-

obexftp -l Pictures (gives folder content)

obexftp -c Pictures -g "Picture(3).jpg"

or for a music file:-

obexftp -c Sounds -g "Sony Ericsson.mid"

and so on. make sure irda is started by using:-

/etc/init.d/irda start

To send a file to the mobile (put):-

obexftp -c Sounds -p "music001.mp3"

To transfer java games is a similar process, make sure the extension is '.jar' the use the following command:-

obexftp -p MobileInvaders.jar

When transfer is complete the phone will ask wether to save the file in Games or Applications, if it's compatable, then it will ask do you want top run it now?

Anyways, the problem I have is that the transfer is VERY slow, particularly with large (mp3) files - I've tried "setserial /dev/ircomm0 spd_vhi" but it makes no difference - does anyone know how to speed up the ir port?

Cheers.....
