Who knew Windows Mobile was so hackable? Apparently one can customize the SMS application background by simply taking a JPG, naming it sms_bg.jpg, sms_bg1.jpg, and smschatbgr.jpg and simply drop it in the Windows directory of your device.
If that sounds a bit too much work, there are some backgrounds available to download in self-installing cab form in this XDA-Developers thread here.
This hack will obviously do nothing to HTC’s threaded SMS application, but if a clean ROM is your thing you now have it made.
