I am about to upgrade my phone to a Verizon Incredible. One of the sales people in the store told me that when Verizon goes to 4G, I should be able to flash my phone and have it work on the 4G network. Does anyone know if this is that case? Or maybe just a sales pitch. I am wondering if I should wait until 4G rolls out. Hate to do a 2yr contract and be stuck. Thanks!! Malibu.
