bueno... buscando por XDA he visto que un moderador comentaba esto:
The invites are still working.
"For some reason or other, invites sent to GMail addresses are taking 7 hours to be delivered.
Also, the system over capacity error is temporary. They do keep opening registrations for those who invited at random times.
Adam from here is working on an GM script notifier, if he completes it, I'll be able to notify people when registrations are open.
I'm still sending out invites to people who submitted to my form. It's just taking a hell load of time(more precisely around 7 hours) for the invites to go through.
Hope that clears up all the confusion.
Cheers!"
por lo tanto toca esperar a que el correo de invitación nos llegue en unas 7 horas si es real esto que dice el moderador.
muchas gracias a todos!
