so sometime last week I got my Sony Ericsson T610 phone. After the fear that I would be stuck using the default themes on the phone I went out in search of the file format or some information on them. Well shockingly what I discovered was quite cool...
It seems that the file format is in fact a tar file full of GIF/JPEGS and an XML file. So I got out Kate and ark and had a party. The result of this was a KDE theme for the T6xx phones. So I told zack about this and well he obviously thought this was very cool and soon there after Krafy was born. While its not very advanced we can actually load and save valid theme files, as well as manipulate the properties. The task remaining... and one that seems to have sucked up all our efforts is painting the previews. so anyone with a T6xx interested in playing along? 
Too late :-)
I have a Z600 ( young brother of t610 ) and did a Konqi theme too some time ago !!!
Ian, here's what you need add in apache to handle WAP ( in any apache .conf file. I placed on /etc/apache/conf/conf.d/wap.conf ):

i added this...
... to the server with the link, so wap enabled phones can download the theme...
thanks man!
How are you getting the files on and off of the phone?
Do you have a bluetooth piece? I have a T610 and I'd love to play along. Perhaps in a few days when the wife purchases her next laptop
for now...
i have been downloading them to my pda and "beaming" it to the device. i am testing KDEBluetooth too. it seems they have a full OBEX KIO slave that can be used with IRDA to basicly manipulate the phone via IRDA, serial or bluetooth.
one other approach is to use wap, but i dont have the mime types setup for that on the server yet. I will make noise when i do..
Bluetooth
I have the t630 and am using kdebluetooth on Kernel 2.4.26 and a class-3 Bluetoothdongle to send ringtones (my610.com) and themes which works perfectly.
