I'm new here, so I appologize in advance if this isn't the right place to post this. As I mentioned in my intro, I'm looking to get away from my WinMo Touch Pro II. I'm considering one of the new Samsung Galaxy phones and the Beam i8520 sounds interesting. Since no U.S. carrier has picked it up yet, and who knows if/when they will, I'd be willing to pay a little extra to get an unlocked version via grey market. My concern is, will all the features and functions operate on the AT&T network (that's where I am for a while yet)? Obviously voice calling, but how about roaming, SMS, data, etc? Has anyone tried an i8520 on AT&T? Thanks.
