cpl of noob questions

[YouMayLose]

1.) what is "Beam" I've tried searching but cant really get any info on what it actually is and what it does.
2.) On Juicy5 my data connection ALWAY stayed on and I would receive emails to my phone..Now on Mighty's rom and it seems my data connection turns off on its on if not in use and comes back on if say I log the net or go to settings and turn it on, but now I don't recive my emails to my phone I have to actually active sync to my comp to get the emails on my phone..which is pointless concidering if I'm on my comp the emails don't really need to be on the phone any more lol

Thanks for the help and suggestions and as we all know..THIS SIGHT OWNS THE UNIVERSE.
