Verizon looks to be following Sprint and T-Mobile’s lead with their new LG handsets. According to documents obtained by Engadget, the nation’s largest carrier is going to offer the LG Vortex for free, after mail-in rebate. Customers will pay $100 up front and then get their money back a la debit card. As a refresher, the Vortex runs Android 2.2 and should feature a 600MHz processor and 3.2-inch screen. Look for an announcement on this one soon.
