Remember the leaked screenshots of Android 2.1 complete with HTC Sense running on the esteemed Hero? Well now you could recreate that yourself, thanks to a leaked Hero 2.1 Eclair ROM over at xda-developers. The software is classed as alpha, which means you probably don't want to necessarily trust your everyday Android handset with it; for instance, there's no Google synchronization support right now.
There's also no WiFi support, which could be a deal-breaker for many. Fixes are apparently incoming - the sync problem has already been solved, it's just not been rolled into a new ROM yet - and given the software has only been out for a matter of hours it's very much early days.
HTC are tipped to be preparing this update - officially, of course - for a release around the end of 2009, bypassing Android 2.0 altogether. More screenshots here; now is anyone brave enough to try this out themselves?
