Create, Edit And Install Fonts For Se K800

[djtetei]

I still have some questions:
- how can I edit LAYOUT.xml ?
- is there any software i can use to preview the modification i make in LAYOUT.xml, before i upload the file to the phone ?
- is there any software i can use to preview and test how the menu will display the new fonts ?
- what is the difference betwen the .TTF fonts from my PC and the .TTF fonts used by Sony Ericsson engineers on K800 phones ?
- i understood corectly the installation procedure of the fonts presented in my previous post?

I hope to continue this discussion with you because i'm very interested about the procedure used to develope fonts for SE mobile phones.
