The Samsung Galaxy Tab 10.1 launched this past Friday, but only the Wi-Fi version. Verizon Wireless is expected to get the 4G LTE version, but nothing else has been announced.
Recently, a version with AT&T radios as passed the FCC, but the question is if it will be released by AT&T. Recent rumors are suggesting that Bell network in Canada will be getting the Tab 10.1. If I were a betting man, I would have to say that this FCC approval means that you are going to see it launched up north in the very near future.
