I am new to this whole theming thing and recently I downloaded some themes onto my computer.
However I can't get any instruction to how I am supposed to transfer them onto my phone.
They have come onto my computer but I can't view them as they are in THM form(thumbnails) and are just sitting on my PC waiting for something to do.
Can anyone suggest anything?

you need to download the sony ericsson theme creator software at sony ericsson site to view downloaded themes on your computer....

and if you have already installed the PC suite for sony ericsson phones you just copy the themes to the themes folder of your phone using the USB cable that comes with your phone kit

you need to download the sony ericsson theme creator software at sony ericsson site to view downloaded themes on your computer....sony ericsson theme creator (ver 3.06)

Many thanks for that.I'll try it and let you know.

I tried that and it works fine for Sony Ericsson themes from their site,but not for themes downloaded from Mobile9

Uploading with USB Cable

Firstly, ensure that your mobile phone is connected via USB to your computer. IF you are doing this for the first time, then make sure your Desktop installs the phone correctly so that it is quickly recognised in the future.
It is easy to firstly open the folder where your downloaded theme is located. Leave this window open and then open either Windows Explorer or My Computer. From here you will now need to locate the 'removable drive' that is your mobile phone Once you have opened this file, you are presented with some folders. Each make up a part of the file system on your phone. Simply locate the folder that contains all the themes already on your phone (this folder is usually titled themes). Open this folder, and you will see all the installed themes on your phone. Next we simply need to copy (or drag) the theme into this folder. You can do this by right clicking on the theme and selecting 'copy' and then pasting this into your phones 'theme folder'. Or you can drag the theme to copy it. Do this by simply selecting it from its original location, and 'dragging' it into the phones 'theme folder' Once you have done this with your files, simply close the window, and safely unplug your phone from your computer, the theme is installed on the phone and ready to be set!

Many thanks, I'll try this tomorrow-I need some zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz's
