I will be waiting for the TMobile version, I am ready to jump ship from ATT. Hopefully they will get the customizations as well. And hopefully by the time that rolls around there will be some additional options.
IF I HAD to get one at launch from ATT using the existing customizations I'd go black front panel, dark blue back panel with the silver accents.
Ideally I'd like dark gray front and back with dark blue accents, currently not available under the existing options.
