Chatzvr4 has ROM # 3.03.651.4, which IS the WM v6.1 update. It's his msie, which is probably pIE, that's still 6.0, but that's the latest available for pIE. Still, Hooover is right about considering the custom ROMs available at PPC Geeks. My recommendation is that you install Opera Mobile 9.5, build 19xx, leaked from Diamond, for an unbelieveably nice Internet experience. I've settled on build 1938, other Vogue users prefer 1957, and there are later versions, but they were leaked from Samsung's versus the 19xx's which are from HTC and seem to work better for Vogue. Here's a good starting link:

Edit: Ugh. Looks like some of those later builds are in fact from HTC Diamond, like 2392 - which I tried before settling on 1938 - but the newest at ppcgeeks are not.
