A late leak this evening has provided some details of what will show at Verizon's 4G press conference. The LTE network is now due to go live on December 5 and will start out with the twoUSB modems leaked earlier. LG's VL600 will be a typical thumb-sized drive, while the Pantech UML290 just spotted in the Engadget leak (shown below) has a unique dual-swivel design to accommodate earlier MacBook Airs and others with tight fits.
