There's a fresh breeze going through HTC HQ at the moment. The company has opened up ROM updates to almost everyone. I say "almost", because you still need your device's serial number to download the updates, but that's a heck of a lot better than the notoriously flaky process of registering your device in the e-Club.
With ROM updates available in the Support section, the e-Club now serves as a hub for mobile content. While only twenty ringtones are up for grabs at the moment, they're surprisingly decent. Four of them are the tunes featured in the Touch Diamond promo videos. The rest are a mix of electronic, folk, rock, hip-hop, and new age beats. You do need to be an e-Club member to download them, but it's free for anyone (even non-HTC customers) to register.
