A few Apple rumors becoming confirmed: the launch date will be a week after an event held on March 7th, and it will include LTE capability on both AT&T and Verizon.
Many enthusiasts (myself included) believe that the only way the LTE antenna would be included is if the battery life isn’t sacrificed. I’m going to bet that the iPad 2 (the current model) will be eliminated entirely, except for a black version at 16GB with no antenna.
