Gee, I don't know but at only pennies a desi from Overlaypro I can't see why anyone would go through the trouble of rolling their own. Then there's Desi.com who even gives you free software.
I'm sure that adding the cost of supplying the desi on to the price of a new phone isn't going to break the bank. If customers want them redone charge then for the time and desi or just refer them to Desi.com. This shouldn't be a non-profit endeavor and it does add that finishing touch.
I suppose I could see using Excel if you could do something that the maufacturer's software can't but come on. Don't know about you but I have better, more profitable things to do than screwing with desi's.
