HTC is tricky tricky. I thought this was going to be easy, but I had to use every bit of my smali hacking knowledge to kick it's ass.
I used a stock 1.45.401.2 (2.3.4 EU OTA) deodexed Rosie.apk to mod from. So this should work on any new major ROM out there (Revolution HD, Leedroid, InsertCoin, Virtuous, my ROM, etc), and likely even work on the up and comping TMO OTA patch.
I haven't swapped out the image because I don't really have a good browser image to match, so you're stuck with the personalize button picture, unless someone wants to provide me with a good one. I'll swap them out np.
