i just found these on ppcgeeks now i know these work for sure on verizon but other tp2 models at your own risk. these are true flip clocks you can watch the time flip.
The first clock is the stock htc one ,white squares with black numbers.
2nd one is totaly clear so you can see your wall paper.
i will link the page for directions if further needed.
also i attached pics of both at the bottom.
1st step,install the eboelzner cab first it is a must to unlock your clock plus it in stalls the white clock weather you want the white one or the clear one you have to install this first it unlocks the clock, install and soft reset, do not uninstall if you want the clocks to stay.
step 2: if you want the clear clock install the crystal cab and soft reset like i said above you have to do step 1 first no matter what. soft reset between both cab installs.
note if you install the crystal clock and you do not like it just go to add/remove programs it will be in there just erase it and soft reset and it will go back to the white and black one if you want it back to original vzw erase both cabs and soft reset thats it.
