Modaco dijo en su foro oficial que no es recomendable instalar la ROM oficial nada más salir porque puede que venga "cerrada".
When HTC finally release the 2.1 update... it's probably not a good idea to install it!
Wait for a repacked version, the 2.1 update will likely ship with a perfected SPL and once you've flashed it, there may be no way back...
