I am attempting to modify my Sprint q home screen as well.

not the same level of support out there for Sprint as VZN. Never tried coding XML before... going to get a book today... Maybe someone can share quick tips to mod-ing the VZN xmls out there to get them to work for Sprint.
Also I am looking to create fixed app links... maybe just my favorite 6-7... and to change the assignment of the START key. Any help would be appreciated.
