One of the reasons we (2 daughters and me) got the Droid was as a backup for laptop internet access when a hotspot isn't available or the home network is down. I've searched on the topic and I've read in some threads that rooting is needed for tethering and Wifi and read in others that it is not. QUESTION 1 - Can someone clarify whether rooting is required to tether? QUESTION 2 - PDANet seems to be the front runner app and I'm considering the full paid version. Does anyone know if PDANet plays nice with VPN software? Thx!
