Well that didn’t take long. Earlier this week we saw the announcement of the HTC Desire and now a hacked ROM has appeared online. Paul from MoDaCo has uploaded what he calls an alpha leak of the HTC Desire software. As many of you know the Desire features almost identical hardware to the Nexus One, but it comes loaded with HTC’s Sense UI instead of stock Android.

Since the phones are so similar, it is easy to swap out the ROMs and bring the Sense UI to the Nexus One. As noted, “this isn’t even beta so there’s a good chance you won’t want to use this as your main ROM”, but it is still cool to see what is coming next from HTC.

Our friend Csewell has already flashed the Sense UI ROM onto his Nexus One and captured it on video so you can check out the hack without messing up your phone.

It definitely looks slick, but I’ll take plain old vanilla Android every time.
