I have Juicy's R1 HTC Sense ROM Loaded on My Verizon TP...Have Not tested on other Carriers.....
This Cab will remove the white background behind clock.
To install
Copy Cab to Storage Card or TP2
run Cab
Install on Device (Not Storage Card)
Restart HTC Sense (quick way is to slide to settings....personalize....rearrange tabs....make a small change and HTC sense will restart)
