You didn't specify which carrier you're using, but assuming that you're going with Verizon, they require that you get either their $29.95 or $44.95 data plans when you activate the Omnia.

The wifi will work even if the phone isn't activated (mine won't be activated for two more weeks but I'm able to surf the web with wifi) and, for that matter, when the phone itself is turned off.

The USB cable supplied with the Omnia will charge from an Activesync-equipped computer but not from, for example, a powered USB hub that is not connected to a computer. I have seen aftermarket cables that claim to be both charge-and-sync but don't have any firsthand experience with them.

I don't believe any of the software supplied with the Omnia will allow you to screen callers.

Can't answer the other quex, sorry!
