Will this work in the US? If so, how? Does it use it's own number to send messages to your contacts? How will they be able to reply? This is from the Engadget review of the tab and was just wondering how it would work. Thanks!
Messaging, Contacts -- These are pretty self-explanatory. Even though the Tab isn't technically a phone since all the US carriers have restricted its calling ability, you can use the messaging app to send SMS or MMS messages or e-mails to other contacts. Like the others, you've got a two pane view in landscape mode -- you can look at your contacts on the left side and message from the right.
