Well, I didn't do this but we may have an up and coming app developer, dworph, who has come up with an experimental mod if you can't stand the 4.2.2 deskclock and want your old 4.1.x one back. It seems to have some customization available as to colors and such as well. Note, this is experimental but hopefully some will try it and/or other devs can help put the finishing touches on it.
