Ok, i just installed and got wired tethering working on my android eris running xtrrom4.2 and I have VZW as my carrier. is there anything I should know after it's done? I'm new to the whole tethering thing for android and I just need some answers to a few questions... First off, does it charge me for any data usage even though I have an unlimited data package. I think it's awesome that I can get on the internet from my phone wherever I'm at and charge my phone at the same time. I don't want to be using this if it's going to charge me a gazillion dollars after the fact. Also, I just started using it, if I navigate away from the screen on my phone will it turn it off? Say I want to check a message or something.... Is there anything else I should know after the fact? I just don't want to be caught with my pants down if there is something that someone already knows about this application. Thanks in advance, Zynnis.
