Hi, I'm new here. Expecting to get the droid x next month for work. I have a question regarding the wifi tethering. Does anyone know if the droid x can multitask while wifi-tethered. Can it still recieve phone calls? Forgive me if this is a stupid question as I have never owned an android phone/or smartphone for that matter. I just got around to convincing the boss that we all need to get something to increase efficiency, etc. and this came up. Is the $20 extra a month for tethering just to add the wifi tethering, or is it for both wired and wifi? Thanks to anyone who answers.
