HTC Tatto Android 2???

---

Hi everyone,
I'm new to Android having got my HTC Tattoo during the week.
I'm wondering if there is any way to get Android 2 (Eclair) onto my Tattoo? I've googled for it but there's only instructions for the Hero.

I don't care if its a vanilla ROM without Sense UI. I'm just looking for an update to help improve battery life and bluetooth functionality (plus I like to have all the latest versions of things :) ).

I emailed HTC about it and they said they couldn't confirm if the Tattoo was getting the update (which probably means it won't...)
Also, I'd rather not use a buggy beta ROM .

Thanks in advance,
Keith

PS: I know people managed to get a V2 ROM onto the G1 by rooting but I presume it's differen for the Tattoo because the different screen size, addition of FM radio etc.
